Nowadays,  with ever increasing industorial  technologis customers  are looking for products with higher quality and  lower prices. As a result in order to protect  their marketing share, manufactureres continusely are trying to  improve quality while maintaining and even reducing their prices.
In other words all the manufacturer are following a customer based system in their organization.
petrochemical companies as back bone for industry  are not exception and therfore   have developed in this process.
Kumho petrochemical company as well as other similar companies  are devoloping new products in different marketings.
Komho for example produce a new ABS grade for use in refrigratore application in which this product is tailor maded on the base of costumer request.

Easy and economic production process makes this grade an exelent choice for sheet manufacturers. Now Noavaran Aida plastic Co, as a leading manufacturere in refrigratore sheets is using this grade. Increasig rubbery phase content is the main differences of the mentioned grades compared to traditional grades which this improves mechanical and chemical  propeties. Kumho new technology results in 30% increasing impact resistance while the reduction in tensil strength is not considrable (8%).
Furthermore the resistance of this grade against c5 blowing agent which is more corrosive than R-11 is higher than772. Of course increasing of rubber phase affect ont his new grade thermal process smoking
 Based on increasing impact strength and resistance against blowing agent Noavaran Aida Plastic R&D experts decrease  thickness of ABS sheets in refrigerator, and by cooperation some refrigerator factories and positive complementary test results and  no change of  application can decrease 10% of sheet thickness
That is very important factor to reduce the final price of Aida ABS sheet/weight   .
Finally ,based on Kumho recommendation by using this new ABS grade can decline thermal process like thermoforming energy consumption, and cost saving
