(2)PBT products application


PBT products
PBT is a kind of thermoplastics and has advantages of heat resistance, weather resistance, resistance chemical reagents, optimum electrical characteristics, little moisture pick-up and more shine. It’s widely used in electronics and electrical equipment, auto accessories, machineries, household apparatus; PBT along with PPS, PC, POM and PA are categorized as five major extensively-used engineering plastics.
The company’s proprietary, high value-added and high-tech products like chips for bottles of carbonated beverage, water, water vapor, hot filled beverage, edible oil and PBT are in the forefront in terms of quality in the same industry nationwide and win many honors from the state and the Autonomous Region.

Automobile, electrical and electronic industry:
Due to the good processable properties of PBT, a large number of PBT modification technologies are researched and developed at home and abroad. Using nanotechnology, composite technology, polymer alloy and other measures, we can improve the impact resistance, flowability, flame retardant properties of PBT and its compounded products are mainly used for automobile parts, electrical and electronic components as well as decoration items in the car, household electrical appliance housing, more energy, more energy-efficient and more environment-friendly.

Textile industry:
PBT fiber is a kind of polyester fiber, it has the characteristics of high elasticity. Compared with other fiber, softness of PBT filament is better, more easy to process, better elongation and better dyeability , not easily deformed, not easy to be oxidized. In addition to the traditional application in elastic jeans, bathrobe, sportswear, more suitable for making special dress materials or high elastic yarn used for clothing.
Film packaging field:
After the technological transformation, PBT also can be used for film packaging industry, with properties of heat-resistance and resistance to moisture, more extensive application has been foreseen.

 

(3)PBS products application



PBS products
PBS has excellent mechanical property and heat-resistant quality, its thermal deformation temperature and processing temperature are beyond 100℃. Its synthetic materials originate from petroleum and can be obtained from biological resources through fermentation. PBS is the best biodegradable plastic with best comprehensive property recognized in the world to date.
It is applicable to package, tableware, cosmetics bottle and drug bottle, disposable medical supplies, agro-film, pesticides, gradual-release material to fertilizer, biomedical polymer materials, etc.

PBS APPLICATION

PBS resin (polybutylene succinate), molecular formula HO-(CO-(CH2)2-CO-O-(CH2)4-O)n-H, is completely biodegradable and compostable polyester plastic, milk white granules, odorless. Density: 1.26g/cm3, melting point: 114℃, easily dissolved in organic solvent like chloroform; excellent mechanical property same as PP and PE, crystallinity: 30%-45%, using temperature: -30℃-100℃.

Compared with other biodegradable plastics, PBS has excellent mechanical performance, almost same as PP and ABS. Good heat resistance and its thermal deformation temperature is close to 100℃ and even can exceed 100℃ after compounding, which overcomes the shortcomings of low heat resistance temperature of other biodegradable plastics. Outstanding processability allows it to be variously processed in existing plastic processing equipments, it is the best biodegradable plastic in terms of processability in current market and can be blended with a great quantity of calcium carbonate and starch etc to produce cost effective products.

Moreover, degradation of PBS only happens under condition of touching specific microbe that exist in compost and water etc, otherwise it is very stable in stock and use under normal condition. The main raw materials to produce PBS are aliphatic dibasic acid and diatomic alcohol that can be sourced not only from petrochemical products, but also from cellulose, byproducts of dairy industry, glucose, fructose, lactose, etc that will be available after biological fermentation of crops. We can thereby realize green recycling production, “from nature and return to nature”.
