REINFORCED THERMOPLASTICS
Reinforced thermoplastic compounds are products that have excellent mechanical, physical and thermal properties. Their rigidity, resistance to shock and scratches, to chemical products and UV rays, as well as the ease of transformation of the material through molding, are but a few points to take into consideration in the choice of the material that will correspond to the requirements of your application: polypropylene (PP), polystyrene (PS), polyethylene (PE), different mineral charges (CaCO3, talc, mica) and other materials (glass fibre).
Calcium Carbonate
This is the basic category for this class of products. Charged from 20 to 50%, the material has very good mechanical properties, is chemically stable when undergoing UV radiation and has a controlled color. See table.
Talc
This category of products has superior mechanical and thermal properties. It has been conceived to respond to specific demands such as UV rays resistance, color control, flexion and shock resistance. See table.
Glass Fibre
This category of products has better mechanical and thermal properties. It is also easy to transform their physical state through injection. See table.
Mica
For this category of products, it is easy to obtain good mechanical properties as well as surface finishes that imitate natural marble. The color and size of mica is up to the customer. See table.
Charged materials by Mica and Talc:
We have also developed Hybrid products that contain two or more different reinforcement materials in order to obtain the required esthetical and mechanical properties that a specific product necessitates.
