We have the ability to deliver custom solutions supported by molded-in color plastics testing procedures that can help you achieve your design and engineering specifications.

From business machines and appliances to textiles, automotive components and packaging, designers, brand managers and plastics processors rely on our cutting-edge color technology and in-depth technical support through more than 50 global manufacturing sites and regional offices. We collaborate with you to formulate the colors you envision for your products, and have the plastics processing expertise to help you color and manufacture your products efficiently.

Durometer is the international standard for measuring the hardness of rubber, sponge rubber, plastic, and other nonmetallic materials. Many rubbers, soft plastics, urethanes and TPE’s are rated on the “Shore A” scale.

From technologies that brighten and whiten plastic products to ones that make them glow in the dark, there are solutions for enhancing just about any surface.  These brighteners improve the long-term white appearance of finished plastic products.

A COMPLETE PRODUCT PORTFOLIO A full range of Colorant Chromatics technologies includes: • Color and/or additive concentrates • Specialty compounds including conductive, carbon fiber, CNT, filled, glass, carbon, minerals • Additive concentrates including specialty compounds such as UV, acid scavengers, lubricants/mold release, and foaming agents • Pigment dispersions • Inks and additives for processors of high- performance plastics and fluoropolymers HIGH- TEMPERATURE SOLUTIONS/ INJECTION MOLDING Minimum order quantities for color concentrates and compounds for high-performance polymers are as low as 10 lbs. (5kg), enabling you to manage inventory better and order only what you need. This formulation is created for high-pressure injection molding and is integrated directly into plastic materials.

Plastic Waste Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: the ability and time required to consummate the acquisition of Dyneema; our ability to achieve the strategic and other objectives relating to the proposed acquisition of Dyneema; disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; the current and potential future impact of the COVID-19 pandemic on our business, results of operations, financial position or cash flows; changes in polymer consumption growth rates and laws and regulations regarding plastics in jurisdictions where we conduct business; fluctuations in raw material prices, quality and supply, and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; an inability to raise or sustain prices for products or services; information systems failures and cyberattacks; and other factors affecting our business beyond our control, including without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation.

Able to adhere to a range of engineering plastic substrates, Versaflex elastomers often eliminate secondary operations for faster cycle times and reduced production costs. Formulated without plasticizers to increase clarity and flexibility, plus excellent odor and oxygen barrier performance
