Introduction of the properties and hardness of PE board

Time:2019-03-21 Views:5677
The nature of the PE board
The HDPE board (high density polyethylene board) has a melting point of about 130 ° C and a relative density of 0.941 to 0.960. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress crack resistance are also good. The melting temperature is 220~260C. For materials with larger molecules, the recommended melting temperature range is between 200 and 250C.
English name: PE
Product specifications: thickness x width x length 1-100mmX1000mmx2000mm
Chinese name: Polyethylene
English name: POLYETHYLENE
PE board hardness
Adding PP can increase the strength of the point PE board, but it will cause other performance to decrease quickly.
It can be filled with talcum powder. The shape of talc is flake-shaped, so it has higher rigidity, dimensional stability and heat-resistant temperature, and the reinforcing effect is good.
After filling the talcum powder, the product is prone to spots, and the solution is:
1. Modification of talc powder, adding titanate coupling agent, compatibilizer, such as PP or PE acid rod graft corresponding to resin, can greatly increase the filling amount and ensure that HDPE and filler are more Good compatibility. At the same time, suitable lubricants and processing aids are also very important.
2. The filling ratio should not be too high, around 20%.
The main products of Anheda Plastic Products Co., Ltd. are PA board, PP plastic board, PE board, pc board, pom board, ABS board, etc.
