Terpene phenolic resins known as terpene phenol resins, phenol-modified actually terpene resin, by reaction of σ- pinene and phenol or boron trifluoride in the presence of hydrochloric acid from the catalyst. Strong adhesion, cohesion, heat resistance, anti-aging, with resin and rubber compatibility. Softening point 80 ~ 148 ℃, viscosity (150 ℃) 1126mPa · s, non-toxic. A large number of factory outlets terpene phenol resin 803L, shelf Guangzhou City of the rubber trade in raw materials Co., Ltd. supply various tackifier resins such as rosin 138 glycerol, pentaerythritol aliphatic resin 145, 801 tackifying resins, 803L terpene phenol resin, terpene resins, premium rosin, petroleum resin C5 / C9 serves 803L high softening point terpene phenolic resin terpene phenol resins are widely used in hot melt adhesives, pressure sensitive adhesives, coatings, inks, printed circuits, modified plastics, rubber and other industries sector, especially hot-melt adhesives and coatings manufacturers, the shoe glue tackifying resin 803L, use it to increase the product's scalability and flexibility. Especially in PE, PVC and stainless steel terpene phenol resin quality indicators storage ornaments 5 S resin acid, etc. Do terpene electro-sensitive primary storage 803 workers lipid level 3 means rust / 803-L of light heats -P appearance A8 S made of steel with a pale yellow flakes with a 3 under resistant pale yellow 0 the sheet resistance to a, anti - industry color (Gadner) rubber coated so good for the following ethylenically Chak 10 - mastic gum 7 or less like other agents Huang acid value of polyester plastic agents IE good side 45-60 No. unit Do not stick oil 45-60 day S 3 strong force with bags 4L Softening Point (R) oC melting fat do not want to add plastic 145-160L alkyl aldehyde sticky rust deposit in the amount of terpene solvent 145-160 E5 should S Packing: plastic woven bags, paper bags, 25 kg / bag, pay attention to fire prevention heat storage, stored in a cool place. Rosin is yellowish red to yellow transparent solid, 803L modified terpene resin agent, a softening point of 70 ~ 90 ℃, specific gravity 1.070 ~ 1.085, Foshan 803L modified terpene resin, dissolved heat: 15.8kcal / kg, imported 803L terpene -modified resin, heat capacity: 0.54kcal / kg · ℃, thermal conductivity: 0.11kcal / m · h · ℃, volume resistivity: 5 × 1016Ωcm, flash point: 216 ℃. Rosin also has crystalline characteristics, prone to crystallization, in an organic solvent such as acetone crystallization tendency will, crystallization critical temperature of about 100 ℃, crystallization of rosin m.p. 110 ~ 135 ℃, and difficult to saponification. In addition, further having optical activity rosin, rosin Specific rotation control values ??between 0 ~ 15 ° (optimum point + 7 °) is no crystallization phenomena and the lowest tendency to crystallize shoes gum rosin tackifier resin a terpene 803L_ Nangtong 803L _ of the rubber modified resin provided by the Guangzhou City of the rubber trade in raw materials Limited.
