Product Overview

Zheng Bang’s PVC-R is a chlorine chloride clustering polymer that creates transparent, soft products without the need for plasticizers, offering an innovative solution to the many challenges associated with traditional soft PVC products in the medical field. This eliminates the hazards associated with plasticizers, while maintaining key properties including flexibility, tear and scratch resistance, and twisting capabilities. With our state-of-the-art production facilities, experienced R&D team, and first-class laboratory equipment, we can provide customized solutions to meet your specific needs.

Key Features

PVC-R is a unique chlorine chloride clustering copolymer, formed by copolymerizing vinyl chloride with flexible monomers. Unlike traditional PVC formulations that rely on physical mixing with plasticizers, PVC-R achieves internal plasticization within the PVC resin’s molecular chains. Because plasticizers are not required to achieve softness and flexibility, we eliminate the need for plasticizer migration inhibitors.
Plasticizer migration occurs when plasticizers leach out of the PVC material over time, potentially causing health and safety concerns, especially in medical applications. Without the presence of plasticizers, the potential risks associated with plasticizer migration are eliminated, alleviating a common concern among manufacturers of traditional PVC products. PVC-R offers a safer and more reliable option.
PVC-R can be used as a replacement for impact modifiers in rigid PVC formulations, enabling the production of impact-resistant PVC products. This is especially important in applications where a balance of rigidity and toughness is required, such as in building materials, automotive parts and outdoor products. Manufacturers can achieve improved impact resistance without compromising on other desired properties.
Zheng Bang’s PVC-R can be sterilized using various methods including steam, radiation or ethylene, making them suitable for medical use. PVC-R produces soft products with a hardness of 85-95, including food packaging membranes, medical products, soft heterogeneous products and sealing strips.
