polycarbonate (Polycarbonate) to condense PC is
commonly used one kind of achromatic color transparent not qualitative thermoplastic material.Its name originates from its internal CO3 groups and bases.
Melts the systematic name: 2,2 ' - pairs (4- hydroxyl benzyl) the propane gathers the carbonic ether
CAS serial number: 25037-45-0

The chemical property
gathers the carbonic ether to be acidproof, oil resistant.
Gathers the carbonic ether not to bear the ultraviolet ray, does not bear the strong alkali.

Physical property
density: 1.20-1.22 g/cm line expansion rate: 3.8×10 cm/cm°C thermal deformation temperature: 135°C

  Gathers the carbonic ether colorless transparent, heat-resisting, the anti-impact, is flame-resistant the BI level, all has the good mechanical property in the ordinary application temperature.The same performance close polymethyl acrylic acid methyl ester compares, gathers the carbonic ether to bear the impact performance to be good, the refractive index is high, workability is good, needs to increase the anti- medicinal preparation to be able to conform to UL94 the V-0 level.But the polymethyl acrylic acid methyl ester gathers the carbonic ether price to be low relatively, and may through the polymerization method production large-scale component.Along with gathers the carbonic ether scale of production daily expansion, gathers the carbonic ether to reduce day by day with polymethyl acrylic acid methyl ester between price difference.
  Does not bear the strong acid, does not bear the strong alkali, the modification may bear the alkali acidproof.

The production and the application

  gather the carbonic ether are the daily common one material.Because its achromatic color transparent and outstanding anti-shocking, the daily common application has the disc, the spectacle lenses, the thermos, the bulletproof glass, the goggles, the bank guard against glass of, the front light the bullet and so on, the animal basket pet basket.
  Gathers carbonic ether PC also is the material one kind which the notebook computer outer covering uses, its raw material is the petroleum, has become the polyester slice particles after the polyester slice factory processing, again passed through the plastics plant processing to become the end product, from the practical angle, its radiation performance was also better than the ABS plastic, the quantity of heat dispersed quite evenly.

The influence
surpassed 100 research to explore gathered carbonic ether textile fiber bisphenol A leachates in the ecology response. Discoveries and so on Howdeshell in room temperature one kind of internal secretion interferon Bisphenol A(C15H16O2) (phenol methane) looked like from gathers the carbonic ether textile fiber animal basket by the infiltration water, but perhaps it is directs to send the big reason to the female mouse reproductive organ.Are published by vom Saal and the Hughes in August, 2005 in to analyze bisphenol A the leachate low dose influence the document, as if had discovered the suggestion and draws between the conclusion in the financial subsidization to have the relations: The industrial world subsidization research looked favors in has not discovered the heavy writings influence; The government subsidization research favors in the discovery has the significant influence.
Otherwise easy and other materials have

  the chemical action to gather the carbonic ether textile fiber not to be supposed to use the sodium oxide and other alkali cleanser cause to overflow Bisphenol-A (C15H16O2), one kind of known endocrine interferon (influence reproductive system).

To gathers the carbonic ether secure dispute:

  because makes gathers in the carbonic ether to need to increase double phenol A, but double phenol A took one kind of industrial chemicals, on April 18, 2008 by Canada Federal state officially were already recognized for the virulent material, and forbid strictlys in food packing increasing, therefore, gathers the question which the carbonic ether security is noteworthy.


Our country gathered the carbonic ether development suggestion

  to pass through more than 40 years development, our country gathers the carbonic ether still not to form oneself advanced production technology and to have the commercial scale production installment, specially in recent years along with the country cohesion carbonic ether consumption quantity rapid growth, the production and the market formed the uncoordinated supply and demand to be extremely contradictory.Therefore, develops our country to gather the carbonic ether industry is vigorously extremely urgent and essential.
