PVC Gasket

Product Description

PVC (polyvinyl chloride) gaskets are typically made from flexible, durable PVC material and may contain various additives and compounds to enhance their performance. These gaskets are often used in applications involving water, air, and low-pressure gases due to PVC's chemical resistance, low cost, and durability.

Common Components in PVC Gaskets:

1. PVC Resin: The main component, providing the gasket with flexibility and durability.
2. Plasticizers: Added to increase flexibility and make the PVC softer and more pliable. Phthalates are commonly used, though some applications use non-phthalate plasticizers for health and environmental reasons.
3. Stabilizers: To prevent degradation from heat and UV exposure. Lead stabilizers were historically used but are now less common due to health concerns. Modern PVC gaskets often use calcium-zinc or tin-based stabilizers.
4. Fillers: Additives like calcium carbonate may be used to increase the strength and reduce costs.
5. Colorants: These provide color to the gasket, allowing it to be easily identifiable in some applications.
6. Modifiers: Impact modifiers and processing aids may be included to improve the gasket™s mechanical properties and ease of manufacturing.
