urea-formaldehyde-triamine composite granule

It is produced by adding hardener, pigment and other auxiliary additives into urea, formaldehyde and triamine. This kind of high molecular synthetic material is produced under scientific formulations and plasticizing process, stable performance, mature technology. Our products can meet new EU environmental standard and GB13454-92.

Feature and advantages
1) good appearance, bright color, Unlimited range of colors.
2) fluidity can be big or small according to molding requirements for injection molding or compression molding.
3) good performance: impact resistance, non-friable, high hardness, good finish.
4) high antistatic property, excellent arc resistance and electrical resistance.
5) high flame-retardant, strong heat resistance and boiling water resistance.

  1. Non-toxic, odorless and anti corrosion, meeting European environmental requirements.
  2. Application

It is used widely in producing daily use, electrical instrumentation, automotive communication, engineering decoration and so on, particularly in producing high grade electrical switches, high grade sanitary ware, toys, lighting and telephone, it has a universal use.

  1. Choice for molding processing condition

According to different requirements from customers, urea-formaldehyde-triamine composite granule has two types: injection moulding compound and compression moulding compound. Molding processing condition should be based on the product’s size, shape, thickness and the actual situation of injection machine and compression molding machine, selecting proper controlling parameters to produce a good quality finished products, now we recommend relevant parameters according to normal condition:
