What is Polyolefin Elastomers（ POE)?
Polyolefin elastomer (POE material) is a high-performance material from the copolymerization of ethylene and alpha-olefin. Compared to other common plastics such as Low-Density Polyethylene (LDPE), it exhibits excellent elasticity, toughness, and temperature resistance, which are crucial for enhancing the durability and efficiency of products that include POE. These characteristics make POE an ideal choice for applications in the manufacture of high-grade POE/PVC POE products.
POE does not release harmful gases when burned, which makes it environmentally friendly. Moreover, the low density and high elastic recovery of POE improve the overall performance of products incorporating this material.
Polyolefin Elastomers （POE） Material Characteristics
The basic characteristics of POE elastomers are high octene mass fraction (greater than 20%), low density, very narrow relative molecular weight, a certain degree of crystallinity, its structure of crystalline PE exists in the side chain of the amorphous copolymer monomer, the crystalline PE chain links as a physical cross-linking to withstand the load, and non-crystalline ethylene and octene long chain to provide elasticity. Its specific properties are as follows:
Outstanding low-temperature impact resistance
Low specific gravity and cleanliness
Outstanding heat sealability
Excellent compatibility with various base polymers
Excellent flexibility and puncture resistance
Very high inorganic filler properties
Excellent elongation and high elasticity
Good light transmission
Excellent electrical insulation properties
Polyolefin Elastomers （POE）Application in Solar Panels
POE material is one of the core auxiliary materials of solar panels, mainly used for encapsulation film, in addition to common photovoltaic encapsulation materials such as EVA film, EPE film in the cost of the component accounted for about 4-6%, although not high, its service life of the component, photoelectric conversion efficiency is very obvious.
