Additives for Foam Extrusion

When choosing a supplier, it is important to know that the materials you purchase for your operation are of the highest quality and are supported by industry leading technical experts with decades of experience in polymer science.  Amcor, Inc. has become the go-to source for foamers when looking to create new products, solve manufacturing challenges, and enhance material properties.

Corrugation is one such challenge that many extruders face.  Amcor’s corrugation reduction additives include a line of proprietary elastomeric and rheology modifiers that enhance flatness, improve surface quality, and increase lamination speeds.  These low-cost additives can mitigate the need for expensive equipment modifications and allow you to extrude consistently high-quality foam.

Ampro N2 by Amcor, Inc. is a process aid designed to improve surface quality (skin) on polyethylene foam. This process aid significantly increases foam compression strength. Ampro-N2 prevents delayed collapse in large profile foam extrusion and is ideally suited for the production of high-quality foam plank, exercise rollers, and floor underlayment. Ampro-N2 melts without imparting shear heat and in most cases, can be added to the extruder without any process condition adjustments.

Amblend-RV is a proprietary high melt strength copolymer with rheological properties specifically designed to enhance foam resilience and resist set. It is beneficial where softness, resiliency, and flexibility is desired. It can be foamed with physical blowing agents to 1.0 lb/ft3.

Due to our in-depth knowledge of plastic foam, we understand how different physical blowing agents impact the foaming and aging processes.  For over 20 years, Amcor, Inc. has supplied the PE/PP/PS foaming industry with high purity, high quality gases and gas blends. Our gas customers have access to our technical staff’s vast knowledge of foamable resins and additives, the manufacturing processes, and equipment unique to the foam industry. Amcor’s investment in technology and service enables remote tank monitoring. This allows for just-in-time delivery of your blowing agent.

Regardless of what you foam, Amcor, Inc.  is a valuable resource by your side.



Slips and Mold Releases

Slip additives not only improve the manufacturing of films, but also the plastic molding/extrusion process and the end use properties.  Slip additives work by migrating to the surface and improving coefficient of friction (COF).

Are you a film manufacturer looking for a workhorse?

Amslip SCFB-is a slip powerhouse designed with ultra-high clarity film in mind. Compounded with LDPE, this slip is formulated to be twice as effective as a standard fast slip.  Producers can achieve the target CoF by using less than one half as much slip, ie: 0.75% vs. 1.5% addition level.

Amslip F5- is a concentrated additive that allows the slip to bloom to the surface very quickly.  It is typical that the slip will start blooming to the surface during film production with the majority of the slip migrating to the surface within 24 to 48 hrs. Bloom will continue to improve over the next 7-10 days.  This product is ideal for air bubble film and bubble-out bags.

Amslip S5-is a high purity slow slip where a delay in slip bloom is necessary.  Slip properties will not start to reach the surface of the film until 14 days after manufacturing. Use of this product enhances roll conformance and on-line corona treatment.

I'm an injection molder.  Why do I need slip?

Amease FP Internal Mold Release-Effective at low levels (0.5%-1%), this product provides a cost-effective replacement for external, sprayed mold release agents.  Proven benefits include: resin flow and dispersion improvement, faster mold release, and cycle time reduction.

Amcor, Inc. offers a broad variety of slips and mold releases that can be customized to your process, converting, product end use and product life.
