LLDPE (CAS No.None)
- 物化性质
- LLDPE为无味、无臭、无毒的乳白色颗粒或粉末，密度约0.915～0.925 g/cm³，熔点约120～125℃。分子链呈线性结构，无长支链，分子量分布窄，具有不同于LDPE的流变特性。其熔融流动性适应新工艺要求，尤其适用于薄膜挤出工艺。力学性能优异：抗拉伸强度、抗穿透性、抗冲击性、抗撕裂性均优于LDPE，且具有出色的抗环境应力开裂性、抗低温冲击性和抗翘曲性。

Product Name:Linear Low-Density Polyethylene
English Name:Linear Low-Density Polyethylene
CAS No.:9002-88-4
Aliases:LLDPE, PE-LLD
Molecular Formula:(C₂H₄)ₙ
Physical Properties:LLDPE is an odorless, tasteless, and non-toxic milky white granule or powder with a density of approximately 0.915–0.925 g/cm³ and a melting point of approximately 120–125°C. Its molecular chains are linear, free of long-chain branching, and feature a narrow molecular weight distribution, resulting in rheological properties distinct from LDPE. Its melt flow characteristics suit modern processing requirements, especially thin-film extrusion. It exhibits superior tensile strength, puncture resistance, impact resistance, and tear resistance compared to LDPE, along with excellent environmental stress crack resistance, low-temperature impact resistance, and warp resistance.
Uses:It is primarily used for various film products such as food packaging film, geomembrane liners, garbage bags, and shopping bags, where its strength and toughness enable thinner yet high-performance films. It is also widely applied in injection molding and rotational molding products including waste bins, toys, refrigerated containers, fuel tanks, and chemical tanks. Additionally, it is used in pipe and sheet extrusion as well as wire and cable coatings. Its latest application is as impermeable geomembrane liners for landfills and wastewater ponds.
Technical Specifications:
Density: 0.915–0.925 g/cm³
Melting point: 120–125°C
Melt flow rate (190°C, 2.16 kg): 0.2–20 g/10min
Elongation at break: ≥500%
Vicat softening point: approximately 100°C
