Introduction to the properties of BMC thermoset parts

Date | 2022-08-30 11:23:37

BMC thermosetting material parts manufacturer very excellent electrical properties, mechanical system performance, heat resistance, chemical corrosion resistance to carry out performance, suitable for a variety of social molding technology process for enterprises, can meet the performance design requirements of a variety of cultural products for students, so we are increasingly susceptible to network users through the user's favor.


BMC thermoset material parts is a use of thermoset plastic, BMC thermoset material parts which a mixture of a variety of learning inert fillers, fibres to be able to reinforcement, catalysts, stabilizers and pigments to form this thermoplastic engineering plastics, for data compression or injection molding process. A cost-adhesive "putty-like" composite structural material. 


Bulk Molding Compounds (BMC Molding Compounds) are filled and reinforced with short fibres as highly informative, BMC thermoset parts due to fibre reinforcement, usually in length units between 1/32 inch and 1/2 inch (12.5 mm). Depending on the application one ends up getting, the formulated composite building material study allows for precise dimensional control, good flame retardancy and electrical trace resistance in China, high dielectric strength, corrosion and contamination resistance, excellent mechanical equipment properties, shrinkage and low colour model stability.


Bulk Molding Compound (BMC Molding Compound) has an even better flow and excellent insulating and flame retardant properties, making it progressively the ideal people choice for applications where our various problems require some detail and dimensional calculation accuracy. The material is available in a choice of 75 colours and teachers can effectively resist these powder direct spray or water-based enhancement coatings. Characteristics: agglomerated prepreg made from a mixture of short-cut glass fibres and the presence of unsaturated polyester pulp. It is suitable for processes such as rapid forming, transfer mode forming and forming during injection moulding. The resulting relevant product market has certain good mechanical safety properties, high relative dimensional stability, good surface finish, water resistance, oil resistance, corrosion resistance, heat resistance and electrical properties. Extremely good, especially arc resistance up to about 190s.  


1, general working performance: BMC moulding plastic (DMC) ratio is relatively large, between 1.3-2.1; product management appearance is not bright, feel good, feel hard and heavy; with fire to start heating will produce provide a lot of soot and styrene odour; BMC moulding using plastic (DMC) of certain local varieties is flammable, but some commodity varieties are extremely flammable, burning time will not leave many inorganic substances. 


2, dimensional parameters stability: BMC moulding plastic (DMC) of the coefficient of linear expansion of (1.3-3.5) × 10-5K-1, less than other generally divided into thermoplastics, so that BMC moulding plastic (DMC) has a value of high stability of the size of the relationship and size measurement accuracy. Temperature has little effect on the dimensional stability of BMC mouldings (DMC), but the effect of moisture is more economical and serious.  


BMC mouldings will swell when they absorb changes in soil moisture.  The coefficient of linear expansion of BMC moulding compounds (DMC) is also very difficult to match with that of steel and aluminium, so they can be laminated with them.
