In the hot melt adhesive industry, domestic and foreign countries are gradually replacing natural rosin and terpene resins with petroleum resins in order to meet the requirements of disposable products such as packaging and pressure-sensitive adhesive tapes. Petroleum resin as hot melt adhesive with tackifying resin instead of rosin and terpene resin is the current unavoidable development trend.
Types and applications of hot melt adhesives
Hot melt adhesive is a kind of plasticity adhesive, in a certain temperature range of its physical state with the temperature change and change, but the chemical properties remain unchanged, its non-toxic and tasteless, is an environmentally friendly chemical products.
Because of its product itself is solid, easy packaging, transportation, storage, solvent-free, non-polluting, non-toxic type, as well as the production process is simple, high value-added, bonding strength, speed and other advantages of the favor, the main components of the hot melt adhesive: tackifying resin, carrier substrate, oil filler, additives.
Company information
The company's main import and export products include
(1)Rubber Products:Rubber products refers to natural and synthetic rubber as raw materials for the production of a variety of rubber products activities, but also includes the use of waste rubber reproduction of rubber products. The output of synthetic rubber has greatly exceeded the natural rubber, of which the largest output is styrene butadiene rubber.When rubber products are molded, after being pressed under high pressure, the cohesion of the elastomer cannot be eliminated, which often produces unstable shrinkage when the product is molded out of the mold (the shrinkage rate of rubber varies depending on the type of rubber), which can only be eased and stabilized after a certain period of time. Therefore, when a rubber product design at the beginning, regardless of the formula or mold, need to be carefully calculated to match, if not, it is easy to produce unstable product size, resulting in low product quality.
(2)Organic Raw Materials:It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
