application
pbt the hygroscopic property of pbt is very weak. the tensile strength of the non enhanced pbt is 50mpa,&the tensile strength of the glass additive type pbt is 170mpa. too much glass additives will cause the material to become brittle. pbt; the crystallization is very rapid, which will cause the bending deformation due to the inhomogeneous cooling. for materials with glass additives, the shrinkage rate of flow direction can be reduced, but the shrinkage rate perpendicular to the process is basically the same as that of common materials. the shrinkage rate of the general material is between 1.5%~2.8%. the materials containing 30% glass additives shrink between 0.3%~1.6%. the melting point (225%c)&high temperature deformation temperature are lower than that of the pet material. the softening temperature of veka is about 170c. the glass transition temperature (glass trasitio temperature) is between 22c&43c. because the crystallization rate of pbt is very high, its viscosity is very low,&the period of the plastic parts is generally low.

characteristic
the 1. slurry preparation system is used in the production of modified pbt,&the catalyst&additive can be added at low temperature.
pc/abs alloy, pc&abs blends can combine the excellent properties of pc&abs, improve the heat resistance, impact&tensile strength of abs, reduce the cost&melt viscosity of pc, improve the processability,&reduce the sensitivity of product internal stress&impact strength to the thickness of products. the rapid development of pc/abs alloy, the global output of about 800 thousand tons / year, the worlds major companies have developed new varieties of pc/abs alloy, such as flame retardant, glass fiber reinforced, electroplating, uv resistant varieties, espe-lly widely used in the automotive industry, is also widely used in computers, copiers&electrical&electronic components. china has started a research&production of pc/abs alloy materials such as shanghai jieshijie company has been applied to automobile decorative parts, lamp shell&heat appliance shell; development institute of the chinese academy of applied chemistry changchun high heat resistance, high heat resistance&high impact resistance&high heat resistance of the three grade pc/abs alloy material has been a number of domestic automobile manufacturing the company used for front decorative board, instrument panel&box cover&other spe-l material goods. lanzhou university study in pc/abs blend with a high pressure polyethylene compatibilizer, the mixture obtained good flowability&low temperature toughness&modulus is almost not affected, for the production of sheet; domestic researchers in order to reduce the pc/abs interface between two phases, adding impact agent mbs in pc&abs, the degree of the impact of air alloy can achieve very high value, pc/abs/mbs appearance is ivory white, uniform texture, feel good.
