Qingdao Weilian Plastic & Rubber LTD excels in the production of customized products.
We develop and produce essential components for any industry in any desired plastic, rubber or
polyurethane material from EPDM, NBR NR, Silicone, PE, TPV, TPE etc.
1. the property of NR
It has good wear resistance, high elasticity, breaking strength and elongation, But in the air, it is easy
to get age, and it is get sticky when it get in touch with heat, which is easy to expand and dissolve in
mineral oil or gas online, but it is resistant to strong acid, but not to Alkali . working temperature is
2. the property of EPDM
Weather ability, aging resistance, ozone resistance, chemical stability are excellent, and CFCS and a
variety of refrigerants. Working temperature is-50~150
3. the property of silicone
It has excellent heat resistance, cold resistance, ozone resistance and atmospheric
aging resistant.Good electrical insulation performance,The tensile strength and wear resistance are
generally poor and has non- oil resistant. The working temperature is -55~250ºC
4. The property of NBR
Good oil resistance, heat resistance, abrasion resistance, solvent resistance and high - pressure oil,
But it is not suitable for polar solvents, such as ozone, nitro-hydrocarbons, and chloroform.
The working temperature is-40~120 ºC
5. the property of CR
It has good elasticity, wear resistance and atmospheric aging resistance.
It is not afraid of violent distortion and flammability.Chemical stability.
The working temperature is -40~100 ºC
6. The property of FKM
Excellent high temperature resistance,And have excellent chemical resistance,most oil
and solvent (other than ketones and esters).cold resistance is not good.
7.TPV (Thermoplastic Vulcanizate)
It is ahighly vulcanized ethylene propylene ternary rubber (EPDM)
material composed of highly vulcanized EPDM particles dispersed in the continuous polypropylene
TPV thermoplastic epdm dynamic vulcanization elastomer /rubber main features
Excellent aging resistance and good weather and heat resistance
Excellent resistance to deformation;
Excellent tensile strength, high toughness and high resilience
Excellent environmental performance and reusable
Excellent electrical insulation performance
Wide range of hardness
Use a wide range of temperatures
Color diversification, transparent, translucent, light color series,easy to color, easy to shape;
It can be injected or extruded with PP, PA, PC, ABS, PS, PBT, PET and other materials
8.TPE (Tetraphenylene）TPE - thermoplastic elastomer is a new material with high elasticity, high
strength and high resilience.
TPE materials soft to the touch, good weather resistance, no plasticizer, is a non-toxic material.
TPE Is a kind of rubber with high elasticity, high strength, high resilience, and has the characteristics
of injection processing materials
TPE has environmental protection, non-toxic and safe, wide application range, excellent color,
soft touch, weather resistance, fatigue resistance and temperature resistance
Superior processing performance, without curing, can be recycled to reduce the cost, not only can be
secondary injection molding, and PP, PE, PC,PS, ABS and other matrix material coating bonding,
Can also be formed alone.
9.The property for TPU (thermoplasticpolyurethane)
Wide range of hardness: products of different hardness can be obtained by changing the ratio of
each reaction component of TPU,
and with the increase of hardness, the products still maintain good elasticity and wear resistance
High mechanical strength: outstanding bearing capacity, impact resistance
and shock absorption of TPU products
Outstanding cold resistance: the glass transition temperature of TPU is relatively low, and it still
maintains good elasticity, flexibility and other physical properties at -35 ℃
Good processing performance:
TPU can be processed by common thermoplastic material processing methods, such as injection
molding,extrusion, rolling, etc.At the same time, TPU and some polymer materials can produce
polymer alloys with complementary properties
Resistance to oil, water and mold
