Additionally, plastic prefilled syringes can be color-coded for easy identification and customized to meet specific opacities in polypropylene (PP) resin, while laser marking additives can help create precise, solvent-free markings.  Custom PP formulations available in opaque or transparent form

The kit contains translucent polyethylene terephthalate (PET) and opaque/gradient polypropylene (PP) bottles enhanced with effect pigments, laser marking, and printed sleeves. They are available across multiple polymer systems, including PA6, PA66, PC, POM, PBT, PPS, and PK, and provide comparable performance to conventional internally lubricated grades (link to full press release here).

The most commonly GLS recommended color concentrates are based on polypropylene (PP) and thermoplastic polyurethane (TPU). Use low melt flow PP or HDPE.

HB rating for PP, PS, ABS, PC/ABS, PBT, PA, PA-GF, TPU generic resins

Evoluscend™ is effective across a range of high-temperature polymers, including PEEK, PPSU, PES, PSU, PEI, LCP, and PPS, with a maximum service temperature exceeding 150°C.

Custom formulations are available for a full range of resins to cover all wire and cable applications including nylon, PVC, EVA, PBT, PE, XLPE, TPE, PU, PP, and fluoropolymers. 

The new reSound™ NF bio-filled grades are based on polymers such as polypropylene (PP) with 15 to 20 percent bio-based filler.

Masterbatches for Spun-Dyed PP: Remafin™ Fiber Colorants

Available in PC, PPS and LCP formulations, the materials can be customized for customers’ specific needs.
