Products and Applications
Swancor strives to " offer sustainable products and services in the fields of green energy, environmental protection, and safety, to benefit both customers and the planet".
Unsaturated polyester resin
The unsaturated polyester resin series such as SWANCOR 961, SWANCOR 963, and SWANCOR 9601 are all para-benzene type unsaturated polyester resins. These resins have excellent mechanical properties, water resistance, and chemical resistance. Their toughness is better than that of isophthalic resins. They are widely used and can be applied in various molding processes, such as hand lay-up, winding, and casting. It is mostly used in some non-extreme corrosive environments. This type of product can also be prepared into pre-promoted types such as SWANCOR 961-P and pre-promoted anti-sagging types such as SWANCOR 961-TP, etc. to meet the resin requirements of different processes. Among them, SWANCOR 961 and SWANCOR 963 are conventional para-benzene unsaturated polyester resins, which are mostly used in structural layers, water transmission pipes, wastewater storage tanks, etc. SWANCOR 9601 is a double-wall tank certified UP resin, which is quite suitable for the preparation of underground oil storage tanks, double-wall tanks, etc.
