1. What is POE toughener?
There are many types of tougheners. POE toughener is one of them. Its full name is polyolefin thermoplastic elasticity. Polyolefin elastomer is a high-performance polyolefin that becomes rubber elastic at room temperature.
2. What are the components of the toughener POE?
The toughener POE uses a metallocene catalyst to achieve in-situ polymerization of ethylene and α-olefins. Thermoplastic elastomer, in which the polyethylene chain crystallization region (resin phase) acts as a physical cross-linking point and has typical plastic properties. A certain amount of α-olefins (1-butene, 1-hexene, 1-octene) are added. After ethylene, etc.), the crystalline area of the polyethylene chain is weakened and an amorphous area (rubber phase) showing rubber elasticity is formed, making the product have elastomer properties.
POE has the dual characteristics of plastic and rubber and has excellent comprehensive performance. Therefore, POE can be regarded as a bridge product between plastic and rubber. POE in a narrow sense refers to ethylene-octene copolymer [Poly (ethylene-1-octene) or Ethylene-1-octenecopolymer, also known as EOC]. In copolymers of ethylene and higher α-olefins, when the content of higher α-olefins in the copolymer is higher, it becomes a semi-crystalline, low-modulus polymer.
The copolymer of ethylene and higher α-olefins acts as a physical cross-linker through the crystallization of polyethylene segments, thereby exhibiting the behavior of a thermoplastic elastomer.
3. What are the characteristics of POE tougheners
POE toughener is an ethylene-octene copolymer, a polymer blend in which the continuous phase and dispersed phase are separated into two phases. It has the following characteristics:
1. It has both excellent toughness and good of processability.
2. There are no unsaturated bonds in the POE molecular structure and it has excellent aging resistance.
3. POE has a narrow molecular weight distribution, good fluidity, and good compatibility with polyolefins.
4. Good fluidity can improve the dispersion effect of fillers and also improve the weld line strength of products.
5. The price is low and the relative density is small, so the volume and price are low.
6. Excellent heat resistance and cold resistance, and wide range of use.
