It is understood that polyolefin elastomer (POE) is in the form of white granules. It is a high-performance polyolefin that becomes rubber elastic at room temperature. It has low density and It has the characteristics of narrow molecular weight distribution, large bending, high low-temperature impact resistance, easy processing, low glass catalytic temperature, and reusability. These characteristics make it have good tolerance for inorganic fillers, good resilience and flexibility, and its hardness is very low. It is widely used in the field of modified plastics, mainly used for modified and toughened PP, PE and PA are used in the automotive industry to make bumpers, fenders, steering wheels, pads, etc.
Polyolefin elastomer (POE) The specific application product range and functions are as follows:
1. PP modification:
Together with elastomer POE Mixed to improve the impact properties of PP, the modified and toughened PP can be used in car bumpers, car door panels, home appliance casings, office stationery, plastic accessories for battery cars and motorcycles, and PP jelly cups, etc.
2. Improve the performance of PP/PE recycling:
For PP/PE recycling, add POE for blending and granulation or direct injection molding , can be used in plastic pallets, plastic turnover boxes, plastic tool boxes, plastic office desk and chair accessories, beach chairs, etc.
3. Toughening of PA nylon and other engineering plastics, compatibilizer:
POE can be smoothly and effectively combined with peroxide initiation. Maleic anhydride (MAH), glycidyl methacrylate (GMA), acrylic acid AA and other monomers undergo grafting reactions. The resulting grafts are widely used to toughen engineering plastics such as PA, and can also be used as phase Capacitants are used in plastic alloys.
4. Foaming with EVA:
POE has much higher flexibility and rebound than EVA, and foaming with EVA It will have better effects, such as lighter weight, better compression rebound, good touch, uniform and fine cells, high tear strength and other outstanding advantages after foaming. Whether it is molded foam or injection foam after granulation, POE has been widely used in beach shoes, slippers, midsoles of sports shoes, mouse pads, seat cushions, styrofoam materials, insulation materials, cushioning sheets, On foam products such as luggage linings.
5. POE for modification of EVA extruded hose:
Mixed use of EVA and POE added to the extruded hose The inner layer makes the hose have a contamination-resistant seal, requiring lower heat sealing temperatures and higher heat sealing strength. Widely used in vacuum cleaner hoses, washing machine hoses, and drain pipes.
6. Color masterbatch or filled masterbatch:
POE is used as a carrier or substitute for PE in color masterbatch or filled masterbatch Wax can improve the quality of color masterbatch or filled masterbatch.
7. Hot melt adhesive:
POE can replace EVA to produce high-end hot melt adhesive, and the product can be odor-free. Low density, high flow coating properties, good wettability, etc. It can also be used together with EVA.
8. Cable materials:
POE can replace EVA, EEA or EPDM for non-PVC cable sheathing material insulation; in addition, POE The low change rate of hardness and strength can replace EVA or be used together with EVA to produce halogen-free flame retardant cable materials.
9. Membrane products:
Such as PE film, based on POE/LLDPE/CPP blend.
10. Non-woven fabrics:
In order to improve the softness and drape of spunmelt non-woven fabrics, the non-woven fabric production process It is necessary to select the appropriate polyolefin elastomer and add other functional additives. Through formula design, adding a certain proportion of elastomer can greatly improve the performance of nonwoven fabrics, and the product weight can also be greatly reduced. Its softness, static friction coefficient, and dynamic friction coefficient will be significantly improved.
