For the same vehicle, the front windshield weatherstrip must be resistant to aging, the interior trim strips should have low odor, and components used in northern regions must also withstand low temperatures. Materials are not one-size-fits-all; you need to tailor your approach to the specific scenario.

Qinghui Plastics’ Multi-Grade Modified Material Pellet Product Portfolio

A Comprehensive Grade Matrix Covering Multiple Applications

Centered on non-metallic materials for automotive applications, Qinghui has established a relatively complete grade system. Soft‑grade general-purpose extrusion and injection molding PVC, TPV; high‑temperature resistant PVC; low‑temperature resistant PVC; low‑VOC PVC; extruded glossy PVC; extruded matte PVC; rigid alloy PVC; wear‑resistant TPV; high‑temperature resistant TPV; high‑flow injection molding PVC and TPV—essentially covering all the key requirements for common components such as trim, seals, and bright strips.

Low VOC Is a Non-Negotiable Requirement

In recent years, regulations on in-vehicle air quality have become increasingly stringent, with low odor and low volatile emissions having become mandatory criteria for entry into automakers’ supply chains. Qinghui has specifically designated low-VOC PVC as a separate grade, precisely to meet this regulatory threshold.

Customization is more valuable than standard products

No matter how many grades there are, they still cannot keep up with the ever-changing needs of customers. Qinghui’s approach is to develop customized material solutions tailored to each customer’s specific processes and components, while providing end-to-end support across material application, processes, and services, ensuring that both manufacturing processes and equipment technologies are fully addressed.
