Product Description

 Hot Sale CAS No 80-05-7 BPA Solid Bisphenol A for Epoxy Resin Price in Stock



Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has almost no solubility in water. BPA is produced on an industrial scale by the condensation of phenol and another chemicial raw material, and has a global production scale which is expected to reach 10 million tonnes in 2022.
BPA's largest single application is as a co-monomer in the production of polycarbonates, which accounts for 65-70% of all BPA production. The manufacturing of epoxy resins and vinyl ester resinsaccount for 25-30% of BPA use. The remaining 5% is used as a major component of several high-performance plastics , and as a minor additive in PVC, polyurethane, thermal paper, and several other materials. It is not a plasticizer, although it is often wrongly labelled as such.


Application:


 

Bisphenol A Application

 

Polycarbonates
Between about 65-70% of all bisphenol A is used to make polycarbonate plastics, which can consists of nearly 90% BPA by mass. Polymerisation is achieved by a reaction with phosgene, conducted under biphasic conditions; the hydrochloric acid is scavenged with aqueous base. This process converts the individual molecules of BPA into large polymer chains, effectively trapping them.

Epoxy and vinyl ester resins
About 25-30% of all BPA is used in the manufacture of epoxy resins and vinyl ester resins. For epoxy resin, it is first converted to its digl ycide e ther (usually abbreviated BADGE or DGEBA). This is achieved by a reaction with epichlorohydrin under basic conditions.

Some of this is further reacted with methacrylic acid to form bis-GMA, which is used to make vinyl ester resins.

 

Minor uses
The remaining 5% of BPA is used in a wide range of applications, many of which involve plastic.BPA is a major component of several high-performance plastics, the production of these is low compared to other plastics but still equals several thousand tons a year. Comparatively minor amounts of BPA are also used as additives or modifiers in some commodity plastics. These materials are much more common but their BPA content will be low.

 

Plastics
As a major component

* Polycyanurates can be produced from BPA by way of its cyanate ester.
* Polyetherimides can be produced from BPA. They are used in medical devices and other high performance instrumentation.
* Polybenzoxazines may be produced from a number of biphenols, including BPA.
* Polysulfones can be produced from BPA and bis(4-chlorophenyl) sulfone forming poly(bisphenol-A sulfone) (PSF). It is used as a high performance alternative to polycarbonate.
* Bisphenol-A formaldehyde resins are a subset of phenol formaldehyde resins. They are used in the production of high-pressure laminates

 

As a minor component

* Polyurethane foams, and particularly memory foams, sometimes use the diacrylate and dimethacrylate derivatives of ethoxylated BPA as chain extenders.
* PVC can contain BPA and its derivatives through multiple routes. BPA is sometimes used as an antioxidant in phthalates,which are extensively used as plasticizers for PVC. BPA has also been used as an antioxidant to protect sensitive PVC heat stabilizers. Historically between 5 and 10% by weight of BPA was included in barium cadmium types, although these have largely been phased-out due health concerns surrounding the cadmium. BPA diglycidyl ether (BADGE) is used as an acid scavenger,
particularly in PVC dispersions, such as organosols or plastisols, which are used as coatings for the inside of food cans, as well as embossed clothes designs produced using heat transfer vinyl or screen printing machines.
* Bromination of BPA froms tetrabromobisphenol A (TBBPA), which is used as a flame retardant in plastics. TBBPA is mainly used as a reactive component of polymers, meaning that it is incorporated into the polymer backbone. It is used to prepare fire-resistant polycarbonates by replacing some bisphenol A. A lower grade of TBBPA is used to prepare epoxy resins, used in printed circuit boards. Its use is diminishing due to restrictions on brominated flame retardants.

 

Other applications
* BPA is used as an antioxidant in several fields, particularly in brake fluids.
* BPA is used as a developing agent in thermal paper (shop receipts). Recycled paper products can also contain BPA,although this can depend strongly on how it is recycled. Deinking can remove 95% of BPA,with the pulp produced used to make newsprint, toilet paper and facial tissues. If deinking is not performed then the BPA remains in the fibers, paper recycled this way is usually made into corrugated fiberboard.
* Ethoxylated BPA finds minor use as a 'levelling agent' in tin electroplating.
