Rubber Seal Strip Applications:

Rubber sealing strips is used in many applications. Rubber sealing strips are used as seals, filler strip, and bumpers for electronics, aerospace, healthcare, construction,Furniture, door and window seal.

popular applications for solid and sponge rubber sealing stripsinclude gaskets for harsh environments, high temperature sealing applications, door and enclosure seals. Our products specifically can be ringed or moulded to specific shapes and dimensions with a range of high quality specifications awarded by the FDA and LFGB.With a range of colours and continuous lengths you can be sure we can meet your exacting needs.

We manufacture extruded rubber seal strips have” D”,”P”,”T “,”E”, “Y”, ”I” shape strips etc in any custom sizes and shapes.

Rubber Seal Strip are available in the following elastomers:

• Ethylene-propylene (EPR, EPDM)
• Nitrile Rubber (Buna-N/NBR)
• Natural Rubber(NR)
• Polyurethane(PU)
• Silicone Rubber

Properties of Rubber Seal Strip Material:

Rubber Seal Strip used in wide application of various fields, our Rubber Seal Strip offer excellent resilience and sealing for applications involving low temperatures and pressures and mild chemical environments.

Our team of engineers can guide you through the process of selecting the ideal rubber material for your unique Rubber Seal Strip applications:

l EPDM – Ethylene propylene diene monomer, commonly known as EPDM, is an elastomer known for its high durability and versatility. EPDM has excellent resistance to heat, ozone, oxygen and oxygenated solvents, chemicals, animal and vegetable oils, and harsh weather. Stable in low and high temperatures, this material has a service range of -40°F to 250°F and is intermittent to 275°F. Additionally, EPDM can resist polar and steam substances with great proficiency.

Natural (Pure Gum) – Natural rubber is a polymer consisting of isoprene. This soft material has high elasticity, which provides superior physical properties such as resistance to abrasion and low temperatures. Ideal for applications requiring acids, organic salts, and other chemicals, natural rubber is non-toxic and has a temperature range of -20°F to 170°F.

Nitrile (NBR, Buna-N) – Nitrile is a copolymer of butadiene and acrylonitrile. This synthetic rubber material is resistant to various solvents, hydraulic fluids, animal and vegetable oils, and aromatic fuels; nitrile can also diminish the effects of heat aging. Nitrile performs optimally in temperatures ranging from -25°F to 170°F, and it is available in premium, commercial, and FDA grades.

l Silicone – An extremely soft and adaptable material, silicone is composed of polymerized siloxanes. Silicone boasts superior elastomeric properties at both high and low temperatures and is resistant to the effects of ozone, oxygen, aging, ultraviolet (UV) light, and extreme weather conditions. Available in FDA grade, this material was a wide temperature service range of -67°F to 400°F and is intermittent to 450°F.

l Vinyl – Polyvinyl chloride (PVC) is a synthetic plastic polymer commonly used in applications with water or oxidizing agents. PVC material offers excellent resistance to abrasion and weather, and is available in rigid or flexible forms to suit various application needs. This material is ideal for temperatures ranging from 20°F to 160°F.

Most rubber, whether natural and synthetic, is also available in sponge form (cellular rubber) in both open and closed cell grades. Zichen Rubber offers neoprene, nitrile, silicone and Viton in sponge form. Closed cell sponge is available for applications requiring high compressibility, while open cell is available for cushioning applications where sealing is not an issue.

Using material sourced from domestic rubber manufacturers, ZICHEN keeps a large quantity of rubber materials in stock and can provide custom designs and shapes in varying grades, thicknesses and hardness to meet your specific needs.
