Technical Support
Formulation engineering notes, substitution protocols and compliance reviews written for PVC compounders and procurement engineers. Each whitepaper is linked to the grade it discusses, so you can move from the reading to the technical data sheet and to a 1 kg sample request in one step.
High-temperature, low-temperature and application-specific plasticizer engineering.
Engineering guide to TOTM (CAS 3319-31-1) in 105°C and 125°C PVC wire insulation: thermal ageing mechanism, trimellitate formulation guidance, oil resistance and low volatility for automotive harnesses.
