ARCEL ULV HD resin provides non-refrigerated storage and is ideal for higher density applications. This product offers lower molding cycle times for high density applications as compared with standard ULV and is suitable for applications of 1.8pcf and above.

One of the newest ARCEL resins, ARCEL ULV resin was developed to meet the needs of our customers who do not have access to refrigerated storage and those who want to further reduce their pentane and VOC emissions. With single pass expansion, this product is capable of achieving molded part densities as low as 1.35 pcf. ARCEL ULV HD

ULV HD ARCEL ® Resins: ARCEL ULV HD resin provides non-refrigerated storage and is ideal for higher density applications. This product offers lower molding cycle times for high density applications as compared with standard ULV and is suitable for applications of 1.8pcf and above.

LD Ideal for low target part densities, ARCEL LD resin can be used to achieve molded part densities lower than 1.0 pcf (16 g/L). In addition, this product has lower pentane content and offers higher product yield than ARCEL 730 resin. This product helps our customers meet increasingly aggressive cost and sustainability goals.
