Fill can be divided into two kinds of organic fillers and inorganic fillers, such as wood flour, rags, paper and a variety of fabric fibers, the latter such as glass fiber, diatomaceous earth, asbestos, carbon black and so on.
For example, adding phenolic resin to wood powder can greatly reduce the cost of phenolic plastic to become one of the cheapest plastic, but also significantly improve the mechanical strength.
Fillers, also known as fillers, can improve the strength and heat resistance of plastics and reduce costs.
