On May 18, 2018, we visited well-known auto parts suppliers. They need our plasma surface treatment equipment to help them solve the bonding process problems. The current material is PP+EPDM+calcium carbide.PP material has many advantages:
1, The relative density is small, only 0.89-0.91, is one of the lightest varieties of plastic.
2, Good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding process performance is good.
3, With high heat resistance, continuous use temperature up to 110-120°C.
4, Good chemical properties, almost no water absorption, and most chemical products do not react.
5, Pure texture, non-toxic.
6, Good electrical insulation.
7. The transparency of polypropylene products is better than that of high-density polyethylene products.
However, there are also many disadvantages:
1. The product has poor cold resistance and low impact strength at low temperature.
2. The products are susceptible to the effects of light, heat and oxygen during use.
3, Poor coloring.
4, Easy to burn.
5, Poor toughness, high static electricity, poor dyeing, printing and adhesion.
After the PP material was treated by the plasma surface treatment equipment, the surface energy was effectively improved, the bonding problems were solved, and the customer's unanimous approval was obtained. Customer's satisfaction is our aim!
