Simultaneous Translation for Rubber and Plastics

The rubber and plastics chain and where language comes in

The rubber and plastics chain starts in petrochemicals, which supply resins and monomers, passes through compound manufacturers and converters, and ends with industrial customers, with the automotive industry standing out. At each link there are technical meetings with participants from different countries: German and American engineers from global suppliers visit Brazilian plants, buyers negotiate resins with producers and quality teams audit processes.

Language enters all of these meetings, and the cost of a misunderstanding is concrete. A misinterpreted specification can lead to an out-of-standard batch, a rejected sample or a supply contract with clauses different from what each party understood. Simultaneous interpretation keeps the meeting at its normal pace and lets engineers speak in their working language, without pauses to translate.

lingo covers this sector with human interpreters and with AI, and prepares the vocabulary before each meeting. Alex Barros, founder, is a simultaneous interpreter with 21 years of experience.

Supplier qualification: what the interpreter must master

In qualifying a compound supplier, the Tier 1 customer and the quality engineer walk the plant, review procedures and discuss test results. The vocabulary comes from the IATF 16949 automotive standard and its associated quality tools, such as PPAP, FMEA and 8D reports. These terms are often used in English even in meetings in Portuguese, and the interpreter must know when to keep them and when to translate them.

Process and product parameters also appear: cure temperature and time, Shore hardness, tensile strength, elongation at break and compression set. Numbers and units demand extra attention, because a swapped value in one sentence can change the outcome of an approval. The pair of interpreters takes turns to maintain this precision across visits that often last the whole day.

Resin negotiation with petrochemical companies

Buying resins brings together purchasing managers, traders and producers. The vocabulary is commercial and technical at the same time: grade specifications, melt flow index, supply contracts, payment terms and delivery deadlines. In negotiations with global producers, price and volume clauses are the center of the conversation, and the interpretation must be exact on these points.

Brazilian petrochemicals have Braskem as a reference, and the local operations of groups such as BASF and Dow keep frequent contact with teams abroad. When the meeting is between teams from different countries, simultaneous interpretation keeps the negotiation from losing pace. In smaller meetings, consecutive may be enough, and the choice between the two is in simultaneous vs consecutive.

Recycled plastics and environmental audits

Post-consumer recycled content, or PCR, has gained space in plastic product specifications. Environmental audits involve the customer's ESG team, the auditor and the certifier, and discuss material traceability, recycled content percentages and documentation. The interpreter must distinguish similar terms, such as post-consumer and post-industrial recycled material, which have different meanings in a report.

In audits, interpretation also serves the record: what the plant manager said must be conveyed faithfully to the foreign auditor. Preparation includes the audit script and the reference documents, sent in advance.

Plant visits, trainings and equipment

Many meetings in the sector take place inside industrial plants, with machine noise and movement between areas. In these cases, portable equipment and individual receivers let the group move without losing audio, and the on-site technician adjusts the system to the conditions of the venue. lingo serves plants in São Paulo and the region, with ISO equipment and on-site technical support, with no travel fee within the city of São Paulo.

Technical application training follows the same principle. The supplier's engineer presents the product and the customer's team learns to use it, with a practical demonstration. For sessions over 2 hours, the pair of interpreters takes turns, and the training material is sent beforehand to prepare the glossary. The guide to simultaneous interpretation equipment rental in SP explains what the kit includes.

Expanded rubber and plastics glossary

Besides the terms in this page's main vocabulary, the glossary prepared for sector meetings includes the pairs below, among others, adjusted to the topic of each meeting.

• Tensile strength — resistência à tração (tensile strength); elongation at break — alongamento na ruptura.
• Compression set — deformação permanente à compressão (compression set); curing time — tempo de cura (curing time).
• Filler — carga (filler); plasticizer — plastificante (plasticizer); masterbatch — masterbatch (concentrate of additives or pigments).
• Melt flow index (MFI) — índice de fluidez (melt flow index); injection molding — moldagem por injeção (injection molding); extrusion — extrusão (extrusion).
• PPAP, FMEA and 8D — automotive quality tools, normally kept by their English acronym.
• Post-industrial recycled — reciclado pós-industrial (post-industrial recycled); post-consumer recycled (PCR) — reciclado pós-consumo (post-consumer recycled).

How to hire interpretation for the sector

To hire, provide languages, date, venue, number of participants and topic in the automatic quote. The PDF arrives by email and WhatsApp in 60 seconds, and the quote amount is the final amount on the invoice. The minimum lead time is 48 hours, although hiring in advance widens the options and the time to prepare the glossary.

Developing tailor-made compounds

In developing a tailor-made compound, the application engineer, the R&D team and the customer discuss the formulation: the base polymer, fillers, plasticizers, the vulcanization system and additives. The conversation is iterative, with rounds of samples and adjustments, and each round requires everyone to understand the same terms in the same way.

These meetings involve intellectual property. Formulations are industrial secrets, and it is common for the customer to require confidentiality before sharing data. lingo signs an NDA valid for 5 years before receiving any material, and Alex Barros does not accept competing mandates in the same deal. The project glossary is built in advance, from the presentations and technical data sheets received.

Most common languages and combinations in the sector

Because the local operations of Lanxess and BASF originate in Germany and Dow in the United States, the most frequent combinations involve English and Portuguese, and, in meetings with German teams, German and Portuguese. In many cases the meeting's working language is English, but some participants prefer to express themselves in German or Portuguese in technical moments, and interpretation ensures no one is left out of the conversation.

When the event involves more than two languages, each output language has its own pair and its own channel. The guide to multilingual simultaneous interpretation details how these events are organized.

Vocabulary pitfalls in the sector

• Terms kept in English: acronyms such as PPAP, FMEA and IATF are often used untranslated, and the interpreter must follow the group's usage.
• Words with their own technical meaning: cura (curing), carga (filler) and composto (compound) have specific meanings that differ from everyday use.
• Scales and units: Shore hardness has different scales, and the interpreter must always keep the scale cited by the speaker.
• Post-consumer and post-industrial recycled: similar expressions, with different consequences in audits and specifications.
• Company names and product grades: should be sent in advance, with the desired spelling and pronunciation.

For this reason, sending data sheets and presentations in advance makes a difference. The sooner the material arrives, the more complete the glossary, and the fewer questions arise during the meeting. To organize the sending, the guide how to prepare your event gives the step by step.

Human interpreter or AI in the sector

lingo offers both options. In supplier qualification, compound development and resin negotiation meetings, where a wrong term can change a specification or a clause, the human interpreter with prepared vocabulary is the safest choice. In lower-risk trainings and informational meetings, AI can serve at lower cost. The comparison of cost and risk is in ROI of simultaneous interpretation.
