Frequently Asked Questions

What is a nucleating agent?

A nucleating agent promotes the crystallization of semi-crystalline plastics like PP and PE. It increases crystallization rate and density, leading to improved stiffness, clarity, heat resistance, and faster molding cycles.

Are BGT products FDA approved?

Yes, several of our clarifying agents, including BT-9805, are FDA-compliant for use in food-contact applications. Always verify specific product documentation for compliance details.

Can I use BT-300 ink remover without heating?

Yes, BT-300 is a liquid formulation designed to remove printing ink from PP and PE films at ambient temperature, making it energy-efficient and easy to integrate into recycling lines.

What polymers are compatible with BT-20?

BT-20 is compatible with a wide range of polymers including PP, PE, EVA, POE, PA (nylon), PES, POM, and TPT, making it a versatile stiffening nucleator.

How does optical brightener improve plastic appearance?

Optical brighteners like OB, OB-1, and CBS-127 absorb UV light and re-emit blue light, counteracting yellowing and enhancing whiteness and brightness in plastic products.
