Introduce how PP plastics can resist low temperature. PP plastics are often embrittled at low temperatures, and the products are prone to cracking. How to improve this, so that it can be applied to various fields more widely.
Toughening and cold resistance Method 1: Blending with polyethylene PE, the low temperature embrittlement temperature of PE can reach -70 degrees. Adding proper amount of PE can change the low temperature resistance of PP, but excessive addition of PE will affect the hardness of PP products.
Toughening and cold resistance method 2: Polyolefin POE toughening, POE has the general characteristics of thermoplastic elastomer, low density, excellent heat resistance, cold resistance, wide temperature range, and is an ideal material for changing PP low temperature resistance, usually added 3 %-15% can make polypropylene PP reach -20 degrees, use POE cold resistance to toughen PP, not only change the original PP is more resistant to low temperature, but the impact determination will also increase.
Toughening and cold resistance method 3: EPDM toughening EPDM, the most important characteristics of EPDM is its superior resistance to oxidation, ozone and erosion, and low temperature embrittlement resistance. EPDM cold resistant particles are used to change PP cold and cold resistance. Sex can reach -40 degrees. The cost is relatively higher than the POE, but the performance is incomparable.
