D | LDP | IV | Gaskets |
Glyptal is a type of polyester resin used primarily in the production of paints and lacquers. It is known for its excellent durability and resistance to chemicals and weathering, making it ideal for coating applications.
Neoprene is a synthetic rubber used in the manufacture of gaskets, seals, and protective coatings. It is resistant to oil, heat, and weather, making it highly suitable for applications where durability and flexibility are needed.
Acrilan is a type of acrylic fiber commonly used as synthetic wool. It is lightweight, warm, and resistant to wrinkles and shrinking, making it ideal for use in clothing and textiles.
Low Density Polyethylene (LDPE) is a polymer used in the production of flexible pipes, bags, and containers. It is known for its flexibility, low-density structure, and resistance to chemical attack, making it suitable for flexible piping systems.

The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
