Thermoforming

Polystyrene – Our products for polystyrene have been designed to improve productivity, reduce material cost and increase stiffness when running sheet and thermoforming. For foamed polystyrene sheet, we have developed a highly effective nucleating agent to optimize cell growth and distribution.

SDS TDS

StyroCal™ HP

76% of a 1 micron CaCO3 in polystyrene

Highly effective in HIPS applications for improving sheet stiffness and increasing productivity. Use at 5-25% by weight.

SDS TDS

StyroTalc™ 51

50% of a fine particle size talc in polystyrene

Optimize cell nucleation, growth, and distribution. Typically used at 1-3%.

Polypropylene – We have developed products suitable for a wide range of polypropylene sheet applications offering both calcium carbonate and talc concentrates. Both types of minerals offer unique property gains and selection depends on the targeted performance. In addition, all of our mineral concentrates continue to offer significant raw material cost savings and can be added to existing resin systems up to 50% by weight.

SDS TDS

HiCal™ LM

80% of a 1 micron CaCO3 in a polypropylene homopolymer

Ideal for maintaining stiffness and optimizing heat deflection temperatures.

SDS TDS

HiCal™ LC

80% of a 1 micron CaCO3 in a polypropylene copolymer

Copolymer can help with impact properties for targeted applications.

SDS TDS

HT6HP

60% talc in a polypropylene homopolymer

Talc in HPP is the ideal mineral for optimizing stiffness and rigidity, for products that will be seeing more exposure to higher heats.

SDS TDS

HT6P

60% talc in a polypropylene copolymer

Talc in CPP can help balance stiffness and impact properties in some applications.
