Characteristics and identification methods of EPDM sealant strip

EPDM EPDM sealant strip

1. Light weight, strong toughness: light weight and strong toughness

2. Thermal insulation: low thermal conductivity, excellent thermal insulation

3. Non water absorption: with independent bubble structure, the water absorption is very low

4. Good cushioning and impact resistance, which can be used as cushioning material

5. Good weather resistance. EPDM sponge can pass ozone resistance test (50pphm * 40. C * 72h)

EPDM rubber sealing strip is a very common type of sealing strip. So how to identify the EPDM adhesive strip?

1. Taste. The secondary rubber strips will have a certain odor, especially pungent. Normal rubber and plastic sealing strips will only have the smell of plastic, and even better quality ones will not smell at all.

2. Appearance. The appearance of the sealing strip is very rough, and the handle is also very hard. There is no tension. On the contrary, the good ones are glossy, soft and tensile.

3. Specific gravity. The secondary sealing strip has a particularly heavy specific gravity, because the filler used in the production is heavy calcium or talc powder, which will increase the specific gravity of the sealing strip, while the good sealing strip will directly use light calcium carbonate as the filling material.
