Types of Rubber Materials We Use

Natural Rubber

Natural rubber is one of the most flexible rubber materials, making it useful for custom molded parts that require elasticity and resilience.

SBR Rubber

SBR rubber is a cost-effective general-purpose compound with good water resistance, commonly used in seals, gaskets, and molded parts.

EPDM Rubber

EPDM provides outstanding resistance to weather, UV, and ozone, making it a dependable material for outdoor and automotive parts.

Nitrile Rubber (Buna-N)

Known for its resistance to oil and fuel, nitrile rubber is a versatile choice for gaskets, seals, and molded rubber parts.

Fluorosilicone Rubber

Fluorosilicone rubber combines silicone stability with fuel and oil resistance, making it valuable for seals and parts in aerospace and automotive.

Fluoroelastomer Rubber

Fluoroelastomer (FKM/Viton®) rubber withstands heat, chemicals, and oils, making it ideal for custom molded components in demanding environments.

Silicone Rubber

Silicone is valued for its temperature stability and flexibility, ideal for parts requiring consistent performance in extreme conditions.

Neoprene Rubber

Neoprene offers excellent weather and abrasion resistance, making it suitable for both indoor and outdoor applications.

Urethane Rubber

Urethane rubber offers excellent wear resistance and tensile strength, providing long-lasting performance for seals, gaskets, and molded parts.
