Exploring Silicone Rubber

     Silicone Rubber is an inorganic synthetic elastomer made from a crosslinked silicon-based polymer reinforced with filler. Silicone Rubber is kind of odorless, tasteless and non-toxic.It offers a unique combination of chemical and mechanical properties organic elastomers cannot match. Silicone rubbers consist of long-chain polysiloxanes and various fillers, such as pyrogenic silica. They can be converted into silicone elastomers by vulcanization.

Silicone Rubber burdens unique properties including excellent thermal stability, consistent electrical properties, resistance to compression set, chemical inertness, release ability, flame retardant and long service life.Silicone Rubber obtained by vulcanizing of the product can be widely used in industries of construction, electronics, astronautics, automobile and medicine. Silicone Rubber is applied for insulation, damp proof, shockproof sealing and embedment in electronic devices and components, construction filling sealing and molding of rubber and plastic products and crafts. It can also be used in ablation-resistant coating, moulage and separant, etc.

What is Pentaerythritol

   Pentaerythritol is combustible, and vulnerable to general organic acid esterification. It is also called Monopentaerythritol. Pentaerythritol can be soluble in water and slightly soluble in alcohol. However, Monopentaerythritol is insoluble in benzene, ether and petroleum ether etc. Pentaerythritol is mainly used in the coatings industry to manufacture alkyd resin coating. It also makes the coating film hardness, luster and durability. Pentaerythritol is the raw material of pine resin.

The surface energy of PERE is quite low which is the factor in making it useful as a tackifier in some adhesives. PERE mainly used as a tackifier in hot melt adhesives, solvent borne adhesive, building and construction adhesives and etc.Pentaerythritol provides excellent heat and aging stability, improved resistance to oxidation, polymer compatibility, good skinning resistance and better retention of color.It is used as a tackifier in adhesives industry.Rosin Pentaerythritol Ester is widely used in printing ink, adhesive, coating industry, etc.

    Chengpeng Chemical Co., Ltd  is  a professional supplier of pentaerythritol series with years of exportation experience.We specializes in the production and research on Pentaerythritol series products, including l Dipentaerythritol , Tripentaerythritol , Sodium formate , Formic acid , Formaldehyde , Pentaerythritol triacrylate , Pentaerythrityl tetrastearate , Pentaerythritol oleate ,Rosin pentaerythritol ester.

Talking About Formic Acid

  Formic Acid got its name from“formica”, the Latin name for ant.It is also known as methanoic acid. Formic acid is also prepared in the form of its esters by treatment of carbon monoxide with an alcohol such as methanol (methyl alcohol) in the presence of a catalyst.It is made by the action of sulfuric acid upon sodium formate, which is produced from carbon monoxide and sodium hydroxide.

Formic acid can be made synthetically in laboratories. In nature it usually exists in the form of a colorless liquid. This liquid freezes at 8.3 degrees Celsius (46.9 degrees Fahrenheit) and boils at 100.7 degrees Celsius. (213.3 degrees Fahrenheit). It has a strong odor and is often described as having a “pungent” smell.Formic acid is an irritating chemical present in the venom of many ant species and in the secretion released from many stinging nettles. It’s dangerous at high concentrations, but at low concentrations it’s very useful.Some of the methanol produced in the body is made from aspartame. The body converts aspartame into aspartic acid, phenylalanine and methanol. The methanol is then converted into formic acid.

Formic acid is a kind basic material in organic chemicals. It is widely used in pesticides industry, leather industry, medicine industry, rubber industry, printing and dyeing industry. Formic acid can also be used directly in a fuel cell.
