The MDS-filled nylon round rod has an opaque black color and meets American Society for Testing and Materials ASTM D5989 and Underwriters Laboratories UL 94HB specifications. MDS-filled nylon offers the same good chemical resistance as unfilled nylon 6/6, but the addition of MDS (molybdenum disulphide) adds strength, increases rigidity, and acts as a dry lubricant embedded into the material to extend product life and enhance wear resistance. This material also maintains its dimensions in changing temperatures better than unfilled nylon 6/6. This material may absorb moisture.Plastic refers to a group of synthetic or semi-synthetic materials that have been engineered to achieve specific properties. The most notable characteristics of plastics are its low weight, machinability, corrosion resistance, and typically good thermal and electrical insulating properties. Certain plastic grades also offer optical transparency similar to glass, low-friction or self-lubricating surfaces, and exceptional impact resistance. Depending on their properties, certain plastic grades can be used as alternatives to metal, glass, and ceramic. Unlike metal, plastic may experience creep, which is deformation caused by longtime exposure to a constant load.Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Impact resistance is the measure of a material’s ability to absorb a shock of energy before breaking.
