Automated & Standardized Manufacturing

Exceptional Durability & Longevity

Versatile Industry Applications

NBR

Nitrile Butadiene Rubber, also called buna rubber, has great resistance to oil and fuel with low cost.

It is widely used in automotive, hydraulic and general industrial equipment, making O-rings and flat rubber gaskets.

However, this material performs poorly under low temperature and ozone exposure.

EPDM

Ethylene Propylene Diene Monomer stands out for excellent water, ozone and weather aging resistance.

It is the top pick for drinking water plumbing, outdoor machinery and sanitary pipe gaskets.

However, it will swell and degrade once touching mineral oil or gasoline.

SILICONE

Silicone, also wrote as VMQ, stays flexible at extreme high and low temperatures with food-safe property.

It is applied to medical devices, food machinery to produce heat-resistant sanitary sealing rings.

However, its abrasion and tensile strength are insufficient for heavy dynamic sealing work.

NEOPRENE

Chloroprene Rubber, also known as Neoprene rubber, balances decent oil resistance and strong tear toughness.

It fits marine, construction and general industry for multi-purpose rubber gaskets and pipe washers.

However, it cannot resist strong polar solvents and concentrated corrosive acids.

FKM

Fluoroelastomer, also referred to as Viton rubber, features premium heat, chemical and fuel resistance.

It serves auto engines and chemical facilities to manufacture high-performance O-rings and anti-corrosion gaskets.

However, it comes with high raw material cost and loses flexibility in freezing environments.

FFKM

Perfluoroelastomer is completely inert to almost all chemicals, heat and high vacuum conditions.

It is customized for semiconductor and aerospace to produce high-purity critical sealing gaskets.

However, it has the highest material cost among all commercial sealing elastomers.

ACM & AEM

Acrylate Rubber & Ethylene Acrylate Rubber keeps stable sealing performance in sustained high-temp engine oil.

It is specially made for automotive transmission systems and heat-resistant oil shaft seals.

However, it shows weak elasticity under low temperature and humid working environments.

HNBR

Acrylate Rubber & Ethylene Acrylate Rubber keeps stable sealing performance in sustained high-temp engine oil.

It is specially made for automotive transmission systems and heat-resistant oil shaft seals.

However, it shows weak elasticity under low temperature and humid working environments.

PTFE

Polytetrafluoroethylene, also named Teflon, withstands all corrosive chemicals with ultra-low friction.

It is used on chemical valves and pipelines to produce anti-corrosion flat gaskets and sealing washers.

However, it barely has elasticity and creeps easily under long-time compression load.

OTHERS

Custom Special Polymer Blends cover a full range of alternative rubber compounds including NR, SBR, IIR and custom elastomer formulas.

We develop tailor-made rubber compounds to fully match all personalized sealing requirements from global clients.

Customized materials require extra lead time for formula testing, sample validation and mass production arrangement.
