UF2 Grade Purging Compound is Ideal for Blown and Cast Film Extrusion Applications as well as Injection Molding. UF2 Grade requires Less Product & Allows Quicker Clean-up. This leads to significant savings.
Asaclean® is the industry leader in commercial purging compounds for thermoplastic injection molders and extrusion. Now Asaclean® introduces its new UF2 Grade purging compound. UF2 Grade is ideal for blown and cast film extrusion applications, as well as injection molding. Like all Asaclean® products, UF2 grade purging compound enables faster changeovers for reduced equipment downtime, resulting in increased productivity and greater cost savings for plastics manufacturers.
In order to increase efficiency and productivity, plastics processors look to accomplish several goals, including fast color and material changes, and effective removal of color and carbon contamination. UF2 grade compound achieves these objectives, as it can be purged through a die without removing it, can effectively remove gels and contamination that is not carbonized, and has excellent compatibility with PE resins.
We recommend UF2 Grade for color changes, material changes, hot runner cleaning and shutdown/sealing. Use of UF2 grade compound requires less product than competing products and results in quicker cleanup. For blown film applications, UF2 Grade purging compound helps manufacturers in blown film applications “hold the bubble,” minimizing downtime & increasing productivity. UF2 also helps hold the parison in blow molding.
Recently, a customer cost-savings analysis of an extrusion polyethylene color change- was performed, on a machine with a 4.5” die and a barrel capacity of 50 pounds, where black polyethylene was being replaced with natural polyethylene for the next run. When the customer’s accustomed “next resin” purging method was replaced with Asaclean®’s UF2 Grade, the results clearly indicated a reduction of machine downtime due to faster changeover and less wasted material. UF2 reduced cost by 65% which lead to an annual savings of over $23,000.
Asaclean®’s UF2 Grade has a processing temperature range of 170°C–320° C (340°F–610° F) This grade requires 0.0004” (0.01mm) clearance for hot runner gates and extrusion dies. Also, it passes through up to 200-mesh extrusion screen packs when only one layer of mesh is used.
