Frequently Asked Questions (FAQ)
What are the main characteristics of HDPE?
HDPE is a high crystallinity, non-polar thermoplastic resin. It features excellent resistance to most domestic and industrial chemicals, does not absorb moisture, and has superior water resistance to steam, making it ideal for moisture and seepage protection.
How does MDPE perform under thermal stress?
MDPE has a melting temperature of 126-135℃ and a thermal deformation temperature of 49-74℃. It is highly characterized by its environmental stress cracking resistance and long-term strength retention.
What makes LDPE different from high-density polyethylene?
LDPE is the lightest variety in polyethylene resin. Compared to high-density polyethylene, its crystallinity (55%-65%) and softening point (90-100℃) are lower. It offers excellent softness, extensibility, transparency, and can withstand extreme cold down to -70℃.
Why choose LLDPE over LDPE?
LLDPE provides significant advantages over LDPE, including higher strength, better toughness, stronger rigidity, and superior resistance to heat and cold. It also offers exceptional environmental stress cracking and tear resistance.
Can PE plastic particles be customized for specific applications?
Yes, PE plastic particles are widely used across various industries and can be fully customized according to specific customer requirements and application scenarios.
