Special Engineering Plastics
Special engineering plastics refer to a type of engineering plastics with high comprehensive performance and long-term use temperature above 150°C. They mainly include polyphenylene sulfide (PPS), polyimide (PI), polyether ether ketone (PEEK), liquid crystal polymer (LCP) and polysulfone (PSF). Special engineering plastics have unique and excellent physical properties and are mainly used in high-tech fields…

Bulk (Dough) molding compounds (BMC/DMC)
Bulk molding compounds are thermoset plastics that are mixed with various inert fillers, fiber reinforcements, catalysts, stabilizers and pigments to form a sticky “putty-like” composite for compression or injection molding. Introduction Bulk molding compound (BMC) is a thermoset plastic that is blended with various inert fillers, fiber reinforcements, catalysts, stabilizers and pigments to form an…

New Plastic
Plastic is a type of material whose main component is natural or synthetic resin, with various additives added. Under certain conditions, it can be molded into shapes and can maintain its shape at room temperature. The development of plastic technology is changing with each passing day. The development of new materials for new applications, the…

Urea-formaldehyde Plastic
Urea-formaldehyde plastic is commonly known as “electric jade”. Plastic made with urea-formaldehyde resin as its basic component. It is a thermosetting plastic. There are mainly four types of urea-formaldehyde molding compounds, urea-formaldehyde foam plastics, cast urea-formaldehyde plastics and laminated urea-formaldehyde plastic sheets. Its surface is smooth, hard, bright in color, arc and flame resistant, and…

Overmolding (Post Forming or Secondary Forming)
Under certain conditions, the profile obtained by one-time molding of polymer materials (such as plates, sheets, rods, tubes) is re-molded and processed to obtain the final shape of the product. Introduction Secondary molding is one of the methods of plastic molding processing. A method that uses plastic profiles or parisons as raw materials to turn…

Foam Molding
In the foam molding process or foamed polymer materials, a honeycomb or porous structure is formed through the addition and reaction of physical foaming agents or chemical foaming agents. The basic steps of foam molding are the formation of bubble cores, the growth or expansion of bubble cores, and the stabilization of bubble cores. Under…
