PVC as a coating layer of the disadvantages
Defects of fluorocarbon coatings as coating layer
The fluorocarbon coatings for general PVDF (poly partial vinylidene fluoride) as matrix resin, mixed with high performance pigments, in the form of spray and the traditional coating process on the surface of the PVC or metal coating. The main performance depends on the quality of PVDF and pigment, in the weather resistance, heat resistance, corrosion resistance.
ABS as a coating layer of the shortage
ABS containing butadiene double bonds, bond energy is low, in the short wavelength UV light irradiation, can quickly lead to bond rupture surface of the powder, discoloration, cracking phenomenon, although now auxiliary market developing, traditional ABS in the change in the process of adding some against a strong UV shielding agent, such as ultraviolet light absorbers and anti UV agent, it can not effectively or greatly improve ABS light weathering of. Figure ABS the late aging color change and surface gloss loss.

HongJinYin industry ASA introduction
Our ASA production process is different from other companies, for one step production. Is used asa primary rubber powder and acrylonitrile, styrene polymer blends, according to customer demand add all kinds of additives, colorants and functional additive a processing.
HongJinYin ASA= primary acrylate rubber and acrylonitrile, styrene pre poly + (acrylic rubber) Acrylonitrile-Styrene additive + agent + high-performance colorant
The process for production of ASA performance has a higher light resistance, weather resistance, impact strength, extension rate and less volatile low molecular chain copies. Performance is better than the other due to the two processing caused by strand breaks, degradation products.
In addition, our company can according to customer specific production process needs and use need to adjust the rubber particle size, content, acrylonitrile content and molecular weight to meet the surface gloss and hardness requirements, for customers special requirements of our company have more spacious adjustment.
HongJinYin ASA in the National Building Materials Testing Center for the rapid aging test 6000 hours, the gray card rating is 4 grade.
the Ten characteristics of HongJinYin ASA
Production status: the surface quality of the material is higher than the corrugated board industry. If the shape of the mold is longer, then it is easy to cause the precipitation of the low molecular weight and adhesion of pollutants, the results will affect the surface effect.
HongJinYin measures: to reduce the surface energy of ASA, by changing the content of the three components and adding more efficient functional class auxiliary agent, more than the general ASA is not easy to accumulate dust. 911002 surface resistivity >1.0*E12
Production status: General Factory Co extrusion equipment were not assigned block and the confluence of the core, only by mold runner design is uniformly coated ASA film, plastic materials and process requirements of higher.
HongJinYin measures: to reduce the ASA melting process, the selection of low molecular weight acrylate rubber, so that it can be used in the weak shear environment under the completion of the.
911002 minimum temperature of 170 degrees
Production status:auxiliary feed from the mold over a short distance, ASA evenly coated in a relatively short period of time.
HongJinYin measures:to improve the ASA mobility, and to ensure that there is enough material to extend the rate of matching, in the same time, the coating is uniform and no melt fracture phenomenon.
911002 >35%, the elongation of >15g/10min
Production status: the mold cavity is deep, need to consider polishing is not enough case, the material is easy to product, the material in the die on the ASA surface caused by scratching.
HongJinYin measures:by changing the size of the acrylic rubber and acrylic acid content, improve the surface hardness of ASA
911002 ASTM >110R (D785)
Production status: PVC filler content of doors and windows are not high, the temperature is not high, easy degradation.
HongJinYin measures: to reduce the initial melting temperature of ASA, and improve the heat resistance, to ensure a long time to stay in a small degree of degradation.
911002 melting temperature <180240 degrees for 5 minutes without obvious degradation
Production status: the vacuum process of PVC, and the PVC is not enough, the system is easy to migrate at high temperature, and it is attached to the surface of the product.
HongJinYin measures:the use of high temperature, low melting point lubrication system, to achieve effective lubrication at the same time, the amount of control.
911002 the lubricating system is used for the combination of long chain carboxylic acid salt and alcohol ester.
Production status: almost all the doors and windows profiles by several surface composition, the surface temperature are inconsistent and ASA in various surface temperature deviation of liquidity inconsistent, resulting in the uneven thickness.
HongJinYin measures:improve the ASA melt strength, improve the heat resistance, in the traditional process conditions of 190--210 degrees, the fusion means no obvious change.
911002 the deviation within the range of 5%
Production status: the traditional production of high - light products is the use of nylon wire round of high-speed polishing. General ASA hardness of the market is low, no high light effect, or high hardness, surface defects are not easy to eliminate.
HongJinYin measures: through the reasonable adjustment of the ratio of three components ASA surface hardness and gloss, mold or mold caused by strain, scratches can easily throw.
