Cleveland, Ohio-based PolyOne Corporation has announced the commercial availability of several new colorants and additives.

The company introduced its new OnColor BIO Colorants and OnCap Additives for use in biodegradable polymers such as polylactide (PLA), polyhydroxybutyrate valerate copolymer (PHBV), polybutylene succinate (PBS), polybutylene adipate- co-terephthalate (PBAT), and starch blends.

“We developed these new colorants and additives in direct response to requests from our customers around the world for products based on sustainable materials,” said John Van Hulle, the vice president and general manager of North American Color for PolyOne colour and additives products and services.

OnColor BIO Colorants are available in a range of transparent and opaque colors, and the additives line includes denesting, antistatic, slip, antiblock, UV protection, blue tone and anti-fog additives.

PolyOne provides OnColor Smartbatch BIO masterbatches, and PolyOne can also customize the colorants and additives to meet specific processing needs.

According to the company, the new product lines are applications such as bags, packaging and bottles, and the colorants meet global composting standards.

PolyOne also introduced the patent-pending PicoTint Liquid Colorants, designed for use with clear thermoplastic engineering resins such as polycarbonate (PC), polymethyl-methacrylate (PMMA), styrene acylonitrile (SAN), clear acrylonitrile butadiene styrene (ABS), glycolized polyester (PETG) and terpolymers.

“We leveraged our in-depth resin and compounding knowledge to create a polymer-based carrier for our liquid colorants. This new technology offers thermal stability and processability that were previously unattainable,” said Van Hulle.

According to PolyOne, PicoTint colorants have excellent clarity and do not affect the physical properties of the clear engineering resin up to 0.5 per cent.

The colorants can be used in extrusion, blow molding and injection molding processes in low let-down ratios, and can also be introduced downstream in the manufacturing process.
