All Custom Gasket counts plastic gaskets among the innovative and quality products it produces. The best characteristic about plastics is that it can be manufactured in a variety of shapes and forms, including sheets, rods, tubes, films, tapes, plates and much more. Its plasticity, durability and low cost is a driving force for various industries to choose plastic-based materials.
All Custom Gaskets’ working inventory of different types of plastics includes:
- PTFE: Also known as Teflon, PTFE is one of the most versatile plastics available. The self-lubricating material has great chemical and corrosion resistance, excellent insulating properties, and a low friction coefficient. Available in sheets, rods, o’rings and tubing, PTFE is used in semi-conductors, insulators, bearings, aerospace and chemical processing industries, and can operate in temperatures from -73 to 260 degrees C (-100 to 500 degrees F). PTFE can further be enhanced by adding fillers, such as glass fibres, to improve its wear resistance and compressive properties.
- Expanded PTFE and Joint Sealant Tape: With the same chemical resistance and temperature ranges as PTFE, expanded PTFE is a softer and conformable material made with pure PTFE resin. It is used for applications with limited bolt load torque, typically in pipelines, hydraulic systems and process piping, as well as applications that are exposed to aggressive chemicals. Also available in a form-in-place sealant tape supplied in spools and various thicknesses, it is ideal for worn flanges and ensures a leak-tight seal.
- UHMW: Known for its very low friction coefficient — the lowest of any plastic — UHMW polyethylene offers resistance to abrasive wear from gritty materials. It is used in cryogenic conditions and is recommended for use in temperatures ranging from -250 to 81 degrees C (-418 to 179 degrees F).
- HDPE: High-density polyethylene has greater hardness and tensile strength than other polyethylene material. It is lightweight, has low moisture absorption, has high UV protection characteristics, and can be easily shaped and formed by standard heat treating techniques.
- Urethane: Known for its durability and resistance to extreme conditions, urethane has several advantages over conventional plastics and elastomers. It offers increased strength, toughness and versatility. Due to its unique characteristics, the pharmaceutical and food industries use FDA-approved Tygothane Tubing, a flexible polyurethane that can withstand rigorous daily use for many applications.
- Phenolics and Laminates: This hard, dense material is made by applying heat and pressure to layers of paper or fabric, impregnated with a synthetic resin. It is half the weight of aluminum, yet it possesses the ruggedness to resist abrasion, friction, impact and material fatigue. Phenolics have special properties that fight off the corrosive action of water and many chemicals, increasing the service life and efficiency of the customers’ parts. Common grades include C, CE, GPO3, G-10 and FR-4.
- Mylar: A polyester film used for its high tensile strength and chemical stability, Mylar is flexible, durable and offers excellent resistance to moisture and certain chemicals. Mylar gaskets act as a barrier to aromas and gases, and are often used for their insulating properties.
- Plastic shims: Shim stock is known for its controlled thickness spacing, electrical insulation and sealing abilities. It is often used in applications where corrosion is a problem.
Other plastic products include: Delrin, Kapton, Kydex, Lexan, Peek, Polycarbonate and more.
