Neoprene Gasket (Neoprene Seal)  ( o ring rubber gasket )

Neoprene is the trade name for Chloroprene which was the first synthetic rubber. Neoprene rubber is an extremely versatile synthetic rubber used for harsh environment applications due to its moderate resistance to oil and petroleum base solvents. Neoprene exhibits good resistance to ozone, sunlight, aging, and other weather elements.

Silicone Gasket (Silicone Seal)  ( o ring rubber gasket  )

Silicone rubber is a high-performance elastomer with exceptional high and low temperature properties. Silicone molded and die cut gaskets can withstand within a temperature range of -75° F to +500° F. The low temperature flexibility of silicone is unmatched by any other elastomer.

Gasket ( Seal)  ( o ring rubber gasket )

Fluorocarbon elastomer  (a trade name of the DuPont™ Corporation) is a high performance rubber compound known for its outstanding resistance to high temperature and broad range of chemicals.  rubber’s permeability and compression set are excellent.  displays good resistance to oils and solvents, aggressive fuels, and concentrated acids.

EPDM Gasket (EPDM Seal)  ( o ring rubber gasket )

EPDM rubber is a copolymer of ethylene and propylene. EPDM rubber is one of the most popular, versatile materials available. EPDM is known for its excellent ozone, sunlight, and heat resistance and exceptionally good weather aging properties. Its distinctive ability to stabilize color and resist harsh weather conditions makes it and ideal choice for outdoor applications.

Nitrile Gasket (Buna-N Gasket) ( o ring rubber gasket  )

Nitrile rubber, also known as Buna-N, is the most widely used elastomer for seals and gaskets. Its properties provide superior resistance to petroleum-based fluids, hydraulic fluids, gasoline, alkalis and acids. Nitrile is the polymer of choice for applications requiring oil and solvent resistance.

SBR Gasket (Red Rubber Gasket) ( o ring rubber gasket  )

SBR rubber is a synthetic polymer, commonly known as “Red Rubber”. SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. SBR is highly resilient and commonly used because it is cost-efficient and has the ability to deform to uneven flange edges. SBR (red rubber) exhibits excellent impact-strength, high tensile strength, abrasion resistance, heat resistance, and sustains flexibility at lower temperatures.

Butyl Gasket (Butyl Seal) ( o ring rubber gasket )

Butyl rubber is a copolymer of isobutylene and isoprene. Butyl rubber has exceptionally low gas, air, and moisture permeability. It offers excellent weathering properties and has outstanding resistance to sunlight, ozone, heat aging, oxygen, abrasion and tearing. Butyl is used in many applications requiring airtight rubber. Butyl rubber has excellent dielectric properties and is resistant to acids and alkalis. 

Natural Rubber Gaskets (Gum Rubber Gaskets) ( o ring rubber gasket   )

Natural (Gum) rubber is an elastic material that was originally derived from milky sap or latex of some tropical plants (specifically the rubber tree). Natural rubber, also referred to as “gum rubber”, has many positive characteristics. It has superior resilience, high resistance to tear and abrasion, tensile strength, good compression set, and molding properties. Natural rubber is soft and displays good flexing qualities at low temperatures.

May be you have some questions

1)Where is the rubber comes from ?
rubber comes from a milky white juice which some trees and plants have instead of sap. This liquid, called latex, can be found in the roots, stems, branches, bark, leaves, and fruit of over 400 different plants. Most latex, however, comes from the inner bark of the hevea, or rubber tree
To get the latex, workers cut narrow slits in the bark of the rubber tree at daybreak, for the latex flows easily when the air is still cool. The latex is then allowed to drip into cups attached to the tree for three hours.

The latex, which is 2/3 water, is then taken to a rubber factory quickly, for it spoils easily. There, it is heated and mixed with acid. This process causes the latex to coagulate, or form solid curds. These curds are crude rubber.

2)What are the colors your factory can make ?
We can make any colors on the pantone cards, what’s you should do is telling me the color numbers you want, then our factory will match the colors for you according to your requirements.

3)How can you make sure the dimensions are correct of the products ?
We have thickness gauges, hardness testers, callipers, tension testers and other instruments to make sure each parts of your products are correct, also we use our CNC machines to produce molds, the precision can reach to 0.01 mm.

4)Can your factory delivery goods on time ?

Yes, we have a very big mold factory, we have 30 Machines and 20 technical staffs to make molds, So we can finish your mold within 5 days after receiving your deposit.

We have 50 general workers to produce products after molds are ready, they work 3 shifts, it is never stop to produce products, so we are confident to finish any order on time.

5) Types and properties of rubber

There are many types of rubber, each with special properties: 
Neoprene Rubber - Good weatherability and resistance to abrasion.

Buna-N Rubber - Resists oil and solvents. Not as weather resistant. Also called nitrile, acrylonitrile, and NBR.

Silicone Rubber - Good flexibility and resistance to ozone, sunlight, and oxidation. Very good electrical insulator. Also called polysiloxane.

Natural Gum Rubber - Superior resilience, tensile strength, elasticity, and abrasion resistance.

Rubber - Resists corrosive environments, with exceptional resistance to heat, aging, weather, ozone, oxygen, and sunlight, plus fuels, solvents, and chemicals. Good flame resistance. Also called FKM.

Natural Latex Rubber - Ultra-elastic has excellent strength and stretchability. Has exceptional tear resistance.

SBR Rubber - Has good abrasion and wear resistance. Also called styrene butadiene.

Vinyl Rubber - Good resistance to water, chemicals, and weathering. Also called polyvinyl chloride (PVC).

Santoprene Rubber - Combines the characteristics of rubber and plastic to produce a material that offers excellent weatherability and chemical resistance.

ECH Rubber - Excellent resistance to fuel, oil, and ozone. Also called epichlorohydrin.

Butyl Rubber - Nearly air and gas tight. Has good weatherability, oxidation resistance, and electrical resistance. Excellent resistance to alkalies and acids. Often used for inner tubes. Also called isobutylene isoprene.

Latex-Free TPE Rubber - Transparent elastomer with gel-like consistency to absorb vibration and conform to irregular surfaces. Super stretchy. Has great tensile strength. This type of rubber is nontoxic and nonallergenic.

Hypalon Rubber - Superior weatherability and resistance to ozone, chemicals, and oil even at high temperatures. Resists flex cracking and abrasion from weather, heat, and chemical exposure. Low water absorption. Also called chlorosulfonated polyethylene.
