Material

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 

-50~70ºC.

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  (TetraphenyleneTPE - 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.


Feature:


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
