This page introduces "transparent materials" of "liquid plastics." (For those who are encountering the Kobayashi Kobazol Division for the first time↓ The Kobazol Division specializes in the development of a wide variety of liquid plastics. We excel in proposing custom brands tailored to the specific needs and desired specifications of our customers, which large companies find difficult to address.) "Liquid plastics" are in a liquid state at the temperatures we typically experience in our daily lives and solidify when heat is applied or a chemical reaction occurs. Among them, "transparent materials" boast unparalleled technological capabilities and product lineups. For example... - Method of solidification: Heating ⇔ Non-heating - Hardness: Ultra-soft (e.g., bait) ⇔ Hard (e.g., stone) - Examples of functional enhancements: Flame retardancy, static prevention, antibacterial properties, weather resistance, shatterproof properties, adhesion, stickiness, compliance with food sanitation laws, biomass content 【Contents (partial)】 ■ Transparent Epoxy Aquarit General Catalog ■ Transparent Urethane Materials ■ Glass Coating *For more details, please refer to the PDF materials or feel free to contact us.

The thermal properties of plastics are greatly influenced by their molecular weight and composition. Soft polyvinyl chloride, in particular, is significantly affected by its composition, and it is necessary to select appropriate materials to meet the required thermal properties. Although thermal properties can be summarized in one term, the necessary performance varies depending on the temperature and time involved, which means the required materials differ. Our soft polyvinyl chloride "Kobazole" is offered in a one-component state that includes the materials necessary for performance manifestation. We also have product numbers with excellent thermal properties available. For more details, please refer to our catalog or feel free to contact us. General thermal properties of soft polyvinyl chloride are also listed in the catalog, and we hope this information will be helpful.
