Established in 1991, HEUNG IL POLYCHEM has produced and supplied various kinds of polyurethane resins starting from commercializing of coloring toner for synthetic leather, thus also contributing to the development of the local community.
Recently, the company has reinforced its new business sections concerning the development of environmentally friendly products, in an attempt to improve the company image as a chemical company through commercializing them in the domestic market.
The company¡¯s flagship sale item, polyurethane resins, was developed for the application of wet-processed synthetic leather, and 1-component PU is a thermoplastic Polyurethane solution. When solvent (DMF) is added to water, it forms a film with a genuine leather-like texture and functions.
The results are excellent elasticity, resistance to abrasion, solvents and chemicals, low temperature flexibility, and permeability.
When Polyurethane solution is immersed in co-solvent composed of DMF and water, it forms a micro-porous layer, due to the difference of diffusion rate between DMF and water, which adds gas permeability, volume, and touch feel which are
similar to those of genuine leather.
According to usage, the company can divide PU resin into several grades of Nubuck, emboss, molding, and dipping - especially for micro- fiber-type, which are varied by controlling cell morphology.
It is composed of value-added goods which can satisfy various needs of users, such as physical properties of high abrasion resistance, hydrolysis resistance, etc.
