VELVETOL® H1000 by WeylChem International is 100% bio-based, high performance polyether polyol made with 1,3-propanediol (Bio-PDO). It is easy to handle, process & transport and has a significantly lower environmental footprint, saving 40% in nonrenewable energy consumption and reducing greenhouse gas emissions by 42% as proofed by an ISO 14000-compliant life cycle analysis. It offers low toxicity, low volatility, biodegradability and high thermal heat capacity. It exhibits hydrolysis resistance, high oxidative stability, low melting point, low viscosity and slow crystallization rates. Shows more resistance against acid and heat compared to PTMEG. VELVETOL® H1000 is suitable for thermoplastic polyurethane elastomers (TPU), polyurethane dispersions (PUDs) and polyurethane thermoset elastomers.

Phenothiazine Prills by WeylChem International acts as a radical scavenger/antioxidant. It is available as yellow to greenish prills. It can be used at high temperatures and under oxygen-free conditions. It increases lifetime of synthetic rubber (chloroprene) in order to improve their durability. Addition of 200-3000 ppm of Phenothiazine Prills is sufficient in most cases to inhibit premature polymerization of acrylic acid, methacrylic acid, acrylates and vinyl compounds and thereby increases their stability during production and storage.
