CASAPAO (AmorphousPolyAlphaOlefin) is referred to as APAO glue, which is a low-molecular-weight amorphous copolymer obtained by using a proprietary catalyst and using propylene and ethylene as raw materials.
APAO is widely used in the following aspects:
1. For APP waterproof membrane. After modification of asphalt by APAO, it can improve the high temperature and low temperature performance of modified asphalt. APAO is widely used in APP waterproof membrane and color tile.
2. For hot melt adhesive. Because APAO has good adhesion performance, it does not need additives when used, and it is an environmentally friendly product. Therefore, it can be used for the adhesion of footwear, luggage, automobile parts, PP, PE materials, and the adhesion of sheets and films. medium, polyethylene carpet and felt bonding, etc.
3. It is used for insulating glass to meet the rubber strip. APAO is added to the composite tape to improve the brightness of the composite tape, make the composite tape more compact, and improve the aging resistance and UV resistance of the composite tape.
4. Used for filling masterbatch of PP and PE. In the filling masterbatch, APAO has both the role of carrier and the role of auxiliary agent. In use, it is usually an equivalent replacement for LDPE and 1F7B grades. And also the amount of polyethylene wax can be reduced, so the cost can be reduced. At present, PP braided silk, PE film and cast film have been successfully used to fill masterbatch production with injection molding products. Due to its good water resistance, it is especially suitable for defoaming masterbatches.
5. For the modification of rubber. APAO is well miscible with EPDM, cis-butadiene rubber and natural rubber. APAO can partially replace EPDM, cis-butadiene rubber, natural rubber and butyl rubber, reduce the cost of mixed rubber, improve the processing performance of products, and improve the weather resistance, oxidation resistance and UV resistance of products.
Features of APAO：
1. Good miscibility. APAO can be well mixed with PE, PP, SBS, EPDM, styrene-butadiene rubber, butadiene rubber, natural rubber, etc. to improve its performance.
2. Good aging resistance. APAO has good anti-oxidation and anti-ultraviolet performance. After APAO is added to the product, it can improve the aging resistance of the product.
3. Good low temperature performance. The low temperature temperature of APAO can reach below -50℃, and the low temperature temperature performance of different grades is also different.
4. APAO is a water repellent and an excellent waterproof material.
5. Due to the moderate molecular weight of APAO, it has both carrier characteristics and auxiliary properties, so it can replace part of the carrier and reduce the amount of auxiliary agents.
