Santoprene Push-In Bulb Seals vs. Flex PVC Push-In Bulb Seals

Santoprene, a thermoplastic elastomer (TPE), is often used with plastic bulb seals because it has excellent compression set. Flexible polyvinyl chloride (PVC), or Flex PVC, can be used instead, but this polymer could over-compress and fail to provide a proper seal. Talk to Vip about your specific requirements.

Dual Durometer Push-In Bulb Seals

Dual durometer push-in bulb seals are co-extruded from the same material (such as PVC) in two different hardnesses, or durometers, as measured on the Shore A scale. Plastic extrusion is a manufacturing process that forces material through a die and creates a product with a unified structure.

Styles and Types of Plastic Bulb Seals

There are many different types of plastic bulb seals:

Round bulb seals have a circular bulb.
Half-round bulb seals have a half-moon shaped bulb instead.
Push-in bulb seals with fins are used in specialty window applications.
