POE (Polyolefin Elastomer) is a polyolef-based thermoplastic elastomer (TPO) made with metallocene catalysts. Its unique molecular structure endows it with both the elasticity of rubber and the easy processability of thermoplastic.
The polyethylene segments in the POE molecular chain form crystalline regions, providing strength and processing performance. The copolymer monomers of α -olefins (such as octene) form amorphous regions, contributing excellent elasticity and impact resistance. This perfect microscopic structure
The structural balance makes POE an ideal choice to replace traditional materials such as EPDM, EVA, and SBS, and it is widely used in plastic toughening, photovoltaic packaging, wire and cable, and other fields.
Outstanding impact resistance maintains excellent toughness at low temperatures, significantly enhancing the impact and tear resistance of the base material. Produce more durable and shock-resistant products, expand application fields and extend product lifespan.
It has excellent toughening effect and good compatibility with polypropylene (PP), polyethylene (PE), etc., and is recognized as the best toughening agent. A small amount of addition can significantly enhance the impact strength of the substrate, achieving a balance between high performance and cost.
The density is extremely low, significantly lower than that of traditional elastomers such as EVA. Realize the lightweighting of products, produce more products under the same weight and reduce costs.
It has excellent weather resistance and UV resistance, featuring outstanding ozone resistance, aging resistance and UV resistance. It is particularly suitable for products that are used outdoors for a long time, such as automotive parts and photovoltaic films.
Non-toxic and harmless, easy to process. It can be processed by thermoplastic methods (injection molding, extrusion, etc.) without vulcanization and has no volatile odor. Improve production efficiency, save energy and protect the environment, and comply with the regulatory requirements in the fields of food contact and medical care.

Typical application fields
POE is mainly used as a key additive to enhance the performance of other materials rather than being used alone.
· Plastic toughening modification:
· Automotive bumpers and instrument panels: Toughened PP to enable them to withstand impact at low temperatures.
· Home appliance shells: Improve the impact resistance of PP and HDPE to prevent cracking.
· Medical devices: Used for manufacturing soft and non-toxic components.
· Photovoltaic encapsulation film
As an upgraded alternative to EVA, it is used in the encapsulation layer of solar cell modules, featuring higher PID resistance, lower water vapor transmission rate and longer service life.
· Wires and cables:
It is used as the base material for halogen-free flame-retardant cable material (TPE), replacing PVC, and is more environmentally friendly and flexible.
· Polymer blending:
It is blended with PP and PE to produce thermoplastic elastomers (TPO/TPV), which are used in automotive sealing strips, hoses, etc.
· Footwear materials field:
Replace part of EVA for the midsole, providing better elasticity and lightweight effect.
