Product Detail

Product Feature

1. HDPE is a kind of high crystallinity, non-polar thermoplastic resin produced by ethylene copolymerization. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the meager section. It has excellent resistance to most domestic and industrial chemicals, and it can resist the corrosion and dissolution of strong oxidants (concentrated nitric acid), acid and alkali salts and organic solvents (carbon tetrachloride). The polymer does not absorb moisture and has good water resistance to steam, which can be used for moisture and seepage protection.

2. MDPE is characterized by environmental stress cracking resistance and long-term strength retention. The relative density of MDPE is 0.926-0.953, the crystallinity is 70%-80%, the average molecular weight is 200,000, the tensile strength is 8-24 mpa, the elongation at break is 50%-60%, the melting temperature is 126-135℃, and the melt flow rate is 0.1-35 g /10 minutes. Thermal deformation temperature (0.46 mpa)49-74℃.

3. Low density polyethylene (LDPE) is the lightest variety in polyethylene resin. Compared with high-density polyethylene, its crystallinity (55%-65%) and softening point (90-100 ℃) are lower. It has good softness, extensibility, transparency, cold resistance and processability. Its chemical stability is good, can withstand acid, alkali and salt aqueous solution; Good electrical insulation and gas permeability; Low water absorption; Easy to burn. The property is soft, with good extensibility, electrical insulation, chemical stability, processing performance and low temperature resistance (resistance to -70℃).

4. Compared with LDPE, LLDPE has the advantages of high strength, good toughness, strong rigidity, heat resistance, cold resistance, etc. LLDPE also has good environmental stress cracking resistance, tear resistance and other properties, and can resist acid, alkali, organic solvents and so on.

Note: PE plastic particles are widely used and need to be customized according to customer requirements in different scenarios.

Frequently Asked Questions

What is HDPE and what are its main characteristics?

HDPE (High-Density Polyethylene) is a highly crystalline, non-polar thermoplastic resin. It features excellent resistance to most industrial chemicals, does not absorb moisture, and offers great protection against steam and seepage.

How does MDPE differ in terms of physical properties?

MDPE (Medium-Density Polyethylene) is known for its environmental stress cracking resistance and long-term strength. It has a relative density of 0.926-0.953, a crystallinity of 70%-80%, and a melting temperature of 126-135℃.

What makes LDPE unique compared to other polyethylene types?

LDPE (Low-Density Polyethylene) is the lightest variety in polyethylene resin. It has a lower crystallinity (45%-65%) and softening point (90-100℃). It is highly valued for its softness, extensibility, transparency, and excellent cold resistance down to -70℃.

What are the advantages of using LLDPE over LDPE?

Compared to LDPE, LLDPE (Linear Low-Density Polyethylene) offers higher strength, better toughness, stronger rigidity, and superior resistance to both heat and cold. It also provides excellent environmental stress cracking and tear resistance.

Can PE plastic particles be customized for specific uses?

Yes, PE plastic particles are widely used across various industries and can be customized according to specific customer requirements to suit different application scenarios.
