Plastic Deep Glazing Channels

In the shower door industry, plastic deep glazing channels are usually made of Flex PVC, a more flexible form of polyvinyl chloride (PVC). Flex PVC is available with an opacity that ranges from clear to opaque and is made with different amounts of plasticizers, additives that impart rubber-like properties.

With its good strength, high abrasion resistance, high clarity, and ability to resist water, Flex PVC is also a cost-effective material for custom plastic deep glazing channels. Although it is sensitive to oxidative and ultraviolet (UV) light degradation, these environmental considerations generally aren’t factors with indoor applications.

Santoprene, a thermoplastic elastomer (TPE), can be used instead but costs twice as much as Flex PVC and extrudes at half the poundage per hour. Santoprene is a TPV that has an environmental resistance that is comparable to that of EPDM, but buyers need to weigh cost against performance.

Plastic deep U-channels for shower door and panels can have interior tongues for additional gripping. They may also have feet-like features at the top of each side. Custom plastic deep U-channels are easy to install and can be pressed into place without tools. On the Vip Rubber and Plastic website, these glazing seals are grouped with other types of plastic extrusion profiles. You’ll find many other products there as well.
