What Is Copolymer? A copolymer is a polymer made up of more than one type of monomer unit. Copolymers are produced by polymerizing two or more types of monomer together in a process referred to as copolymerization. Copolymers produced in this way are sometimes also referred to as biopolymers. What Is the Purpose of Copolymer? The purpose of creating a copolymer is to manufacture a polymer with more desirable properties. Copolymers typically experience a lower crystallinity, higher glass transition temperature, and improved solubility. These characteristics are achieved through a process referred to as rubber toughening. Where Are Copolymers Used? Copolymers can be found in many industries, including in: Car parts, washing machine parts,  water pump parts, water treatment components, furniture parts, etc. What Are the Advantages of Copolymer? The advantages of using copolymers include:  1.High shear resistance.  2.High operating temperature.  3.High corrosion resistance.  4.High impact resistance.  5.High dimensional stability.

Q & A Q. What are the differences and advantages of long fiber materials and staple fibers? A：Long-fiber reinforced composites show excellent mechanical properties compared to short fibers and are more suitable for applications requiring high strength. The impact performance of long fiber composites is 1-3 times higher than that of short fibers, tensile strength is more than 50% higher, and mechanical properties are 50-80% higher. Q. The product is easy to brittle, so changing to use long fiber reinforced thermoplastic materials can solve this problem? A: The overall mechanical properties must be improved. The characteristics of long glass fiber and long carbon fiber are the advantages in mechanical properties. It has 1-3 times higher (toughness) than short fiber , and the tensile strength(strength and rigidity) is increased by 0.5-1 times.  Q. Using a more long fiber reinforced thermoplastic material, will it block the die hole due to the long length of the fiber or not ? A: When using long glass fiber or long carbon fiber, it is necessary to evaluate whether the product is suitable for LFT-G. If the product is too small or the dispensing is not suitable for long fiber materials. The long fiber itself has requirements for the mold nozzle.

What is long glass fiber? Long glass fiber reinforced plastic is on the basis of the original pure plastic, adding long glass fiber and other additives, so as to improve the scope of use of materials. Why filling Long Glass Fiber? 1. After long glass fiber reinforcement, long glass fiber is a high temperature resistant material, therefore, the heat resistance temperature of reinforced plastics is much higher than before without long glass fiber, especially nylon plastics; 2. After long glass fiber reinforcement, due to the addition of long glass fiber, limited the mutual movement between polymer chains of plastics, therefore, the shrinkage rate of reinforced plastics decreases a lot, rigidity is greatly improved; 3. After long glass fiber reinforcement, the reinforced plastic will not stress crack, at the same time, the anti-impact performance of plastic is improved a lot; 4. After long glass fiber reinforcement, long glass fiber is a high strength material, which also greatly improves the strength of plastic, such as: tensile strength, compression strength, bending strength, improve a lot; 5. Long glass fiber reinforced after, due to the addition of long glass fiber and other additives, the combustion performance of reinforced plastics decreased a lot, most of the material can not ignite, is a kind of flame retardant material. Why choose Long Glass Fiber instead of Short Glass Fiber? Compared with short fiber reinforced thermoplastic composites, LFT has the following advantages: • Long fiber length, significantly improve the mechanical properties of products. • High specific stiffness and strength, good impact resistance, especially suitable for automotive applications. • Improved creep resistance, good dimensional stability, high parts forming accuracy. • Excellent fatigue resistance. • Better stability in hot and humid environments. • The fiber can move relatively in the molding mold during the molding process, and the fiber damage is small.

What is the PP materials?  Polypropylene (PP) is often referred to as the "steel" material of the plastics industry because it can be modified and customized to meet unique application requirements by adding additives to PP or by manufacturing it in unique ways. What is the Copolymer PP materials? Compared with PP homopolymer, copolymer polypropylene has improved optical properties, improved impact resistance, increased flexibility, lower melting temperature and thus also lower thermal fusion temperature; meanwhile, it is basically the same as homopolymer in terms of chemical stability, water vapor barrier properties and organ sensory properties. COPO-PP VS HOMO-PP COPO-PP Advantages: good overall performance, high strength, high rigidity, good heat resistance, good dimensional stability, excellent low temperature toughness (good flexibility), good transparency and good gloss.
