*Due to different processing method, above data for reference only.
1. Talcum powder can be applied into PP, PE, PS, PA, ABS, PC, PVC and other resin. Besides costs saving effect, it could significantly improve rigidity, heat resistance, creep resistance performance of plastic, as well as improve size stability by reduce shrinkage ratio.

2. For film products, talcum powder can shield wavelength from 7-25 um, maintain the saved quantity of heat (not loss by diffused infrared), assures heat preservation of agricultural shed.

3. For wire drawing plastic products, fine talcum powder can significantly improve its physical performance. In Jumbo bags production (5% talcum added), breaking strength of talcum added plastic is 4% to 6% higher than pure PP, as well as giving a better elongation at break performance, touch feeling and color to plastic.

4. For production of sunshade net, construction net and fence&protective net which requested for high strength and aging resistance, 10% to 20% talcum powder could significantly improve performance of  chemical stability, UV-resistance and aging resistance.

5. For fishing net products, 5% to 10% talcum powder could effectively avoid twine and adhesion issues. Besides assure the transparent of fishing net, improve visual effect during fishing work, improve fishing capacity.

6.For hollow products, talcum powder can give better physical performance than CaCO, for instance rigidity improvement, less shrinkage ratio and longer useful life. Though the less costs from CaCO but which would cause negative effect to physical properties, and the container will be corrosion if contained acidic materials. Different to CaCO, talcum has strong chemical stability which has feature of acid&alkali resistance, satisfy the performance requirement of sealing, pressure maintaining and drop test.

7. For injection products, talcum powder could effectively improve its mechanical performance, reduce range of sunken which caused by shrinkage of pouring gate and edge. Additionally, it could improve the transparency, appearance effect and hand feeling performance. Talcum powder has premium dielectric and barrier properties, and further minimize magneto-electric radiation effects.

8. For household electrical appliance, talcum powder not only save costs of components production, but also improve quality and appearance effect, especially in properties of aging-resistance, sun-resistance, color fading prevent, thermal insulation, heat preservation, inflaming retarding, sound insulation and light weight, the talcum powder has its unique advantages.

9. For Plastic Pipe&board products, talcum powder could effectively improve the burst pressure of pipe, ring-stiffness and improve size stability. For plastic board, talcum powder will brings positive effect to its crisp property, fire resistance and chemical stability. For Al-Plastic-Al board, talcum powder not only saves production costs but also improve performance of thermal insulation, sound insulation product practicability and mechanical property.

10. Moisture of talcum powder would cause stress concentration of plastic products, and further damage the mechanical properties. For practical application, moisture less than 0.3% is the best selection.
