| 备注说明 | The Melochem 736 Dry Granulated Moulding Compound are based on melamine-formaldehyde resins fortified with high-class cellulose as reinforcement and further modified with minor amounts of special purpose additives, pigments, cure regulators and lubricants.Our Melochem 736 grade is a general-purpose injection grade. Chemical components are chosen with the purpose of minimizing the potential risks to working environment and nature.The Melochem 736 Moulding Compounds can be supplied in most colours from translucent pastels to black.Moulded parts are free from odour, light stable and have good moisture resistance and water absorption and are therefore dishwasher safe.Excellent surface hardness and glossy surface is combined with excellent chemical resistance. Fats, oils and common organic solvents like alcohol and acetone do not attack the materials and they are also resistant to surfactants and weak bases. They will withstand attack from weak acids for a shorter duration.Oxygen index is 40% and is achieved without the use of external flame-retardants. No halogens are present in the composition.The products comply with the requirements of the widely used material specifications :DIN 7708 type 152 and 152.7 (*)ISO 2112 type MF B10 and B11 (*)UL certified(*) included in ISO 14528Fields of application: With unique porcelain-like properties, which are not matched by any other plastic material, the Melochem 736 Moulding Compound is used in a number of household applications like dinnerware jugs ladles, bowls and similar objects.Grade 736 is also used in electrical applications requiring heat resistance and abrasion resistance.Melochem products have a high-class feel and can be manufactured by using productive plastic technology.Melochem products are particularly suited for manufacture of scratch resistance and dishwasher safe products. |
