In doing so, he created the first thermoplastic polymer and gave birth to the plastics industry. The first applications were waterproof coatings for cloth, but the earliest processes were inefficient and expensive, ultimately leading to bankruptcy. John Wesley Hyatt learned from Parkes’ failures. His experiments determined the optimal amount of camphor to efficiently plasticize and mold celluloid into stable finished products. Hyatt developed efficient production technology to produce billiard balls and piano keys, previously made from elephant ivory. Buoyed by these profits, he further improved the process to penetrate the garment market. Applications like ...

They are not automatically interchangeable at low temperature. Same PVC resin. Similar Shore A. Similar phr. Similar tensile and elongation at 23°C. Then the product sees -20°C. And suddenly the “drop-in replacement” needs a much closer look. The mistake is simple: Using room-temperature QC to predict cold-weather performance. For flexible PVC, Shore A is useful. But Shore A is not cold flexibility. Elongation at 23°C is useful. But it is not cold bend. A plasticizer change can affect: • fusion behavior • plasticizer efficiency • modulus at low temperature • brittleness temperature • volatility and mass loss • aging performance • migration and extraction behavior • retention of flexibility after heat aging DINP and DOTP ...
