Automotive and industrial parts made from the wrong elastomer fail early — leaking boots, noisy seals, and VOC compliance rejections cost manufacturers real money. DOWREN supplies TPEE and TPV thermoplastic elastomer grades engineered for the applications that punish weak materials: dust covers, sealing strips, air ducts and hoses. Backed by our production base, QC system and technical team, every batch is delivered with stable specs and export-ready documentation, so your production line never waits.
Decision-makers across Southeast Asia, the Middle East, South America and Africa face three recurring problems:
Pain Point
Quantified Impact
1
Material selection mismatch in hot, oily environments— dust covers and protective boots that fail under heat and oil contact lead to early part replacement and line downtime
Wrong material choice is a leading cause of premature seal/boot failure; rework and replacement costs accumulate fast
2
NVH complaints and heavy rubber parts— traditional rubber ducts and hoses add weight and transmit noise
Optimized elastomer ducts cut weight by up to 30% vs. rubber and reduce airflow noise by up to 9.3 dB in the 5k-12kHz range
3
VOC & compliance pressure— vulcanized materials carry higher VOC, raising rejection risk under EU/export regulations such as REACH and RoHS
Low-VOC elastomer grades are becoming a procurement prerequisite in regulated markets
Differentiation: TPEE vs. TPV — superior oil and temperature resistance for dust covers and boots; TPEE vs. rubber — recyclable, shorter cycle times, lighter.
TPV is produced by dynamic vulcanization — crosslinked rubber micro-particles dispersed in a thermoplastic continuous phase — giving rubber-like recovery with thermoplastic processing.
