Molding compounds are among the most widely traded materials in the world today. Finding a reliable molding compounds supplier is essential for the operation of countless businesses and industries. Undoubtedly, China is the biggest supplier of high quality and inexpensive molding compound parts.
InTouch employs the most recent international standards in developing its molding compound parts inspection and quality control protocols. The following are a few of the most current international standards for molding compound parts:
ASTM D2287-11, ASTM D2115-10 and ISO 1265 Polyvinyl chloride molding compounds, widely used in the production of plumbing and construction products, are among the most widely imported plastic materials from China.
- ASTM D2287-11 is the main international standards used in evaluating the various specifications of vinyl chloride molding compounds. Tests included in the specifications include determine specific gravity, durometer hardness, tensile strength, brittleness, volatile loss, and burning property.
- ASTM D2115-10 covers the method for evaluating heat stability of different blends of vinyl chloride molding compounds.
- ISO 1265 covers the test procedure for the quantification of impurities in vinyl chloride resins.
ASTM D2827-11, ISO 2897-1 and ISO 2897-2Several billion kilograms of polystyrene are used annually throughout the world. Commonly used in foamed and solid state, polystyrene molding compounds are used in the production of plastic cups, insulation and packing materials, CD and DVD cases, disposable spoons and forks, and plastic models.
- ASTM D2827-11 provides the methods for evaluating the specifications of styrene monomers, the main ingredients in producing polystyrene. Tests included in ASTM D2827-11 are used to evaluate aldehydes, purity, polymer, enthybenze, peroxides, ethylbenzene, water and coloration.
- ISO 2897-1 and ISO 2897-2 cover the requirements and test methods for molding compound parts intended for the fabrication of impact-resistant polystyrene products.
ASTM D1045-08 and ASTM D1992-91Plasticizers are essential in enhancing the properties of various plastic materials like in improving the durability and flexibility of PVC pipes and softness of rubber products.
- ASTM D1045-08 covers the test methods in evaluating plasticizers intended for use in plastics.
- ASTM D1992-91 covers the various forms of plasticizers intended for use in the production of rubber products.
ASTM D5948-05e1, ASTM D5224-00, ASTM D6289-08 and ISO 2577Phenolic molding compounds, such as the Bakelite Powder are among the popular forms of thermosetting molding compounds and are widely used in fabricating products with electrical insulating properties.
- ASTM D5948-05e1 covers the specifications for thermosetting molding compounds including phenolic molding compounds, silicone, and epoxy.
- ASTM D5224-00 and ISO D5948 cover the requirements for preparing specimens for compression testing.
- ASTM D6289-08 and ISO 2577 cover the methods for measuring shrinkage of thermosetting molding compounds after the molding process.
