The concentration of APorous expertise is in the thin porous film extrusion. The film thickness capability ranges between 0.5 to 25 mils. Examples of polymers that are produced into thin films are polyamide, polyethylene, polypropylene and fluoro-polymer. APorous also has the capability of laminating porous films onto nonwoven and substrates to improve strength, absorbency and dimensional stability. Much of the APorous product developments are proprietary. Two of the products that can be demonstrated by the APorous laboratory are:
Thermoplastic Food Casing. US Pat. No. 6,589,615.
Wettable Nonwoven Battery Separator.
US Pat. No. 6,495,292.
The term compounding implied the blending of polymers and additives to modify the properties of a polymer and achieve homogeneous mixture. APorous specializes in custom plastic compounding. A twin screw extruder is used to blend resins, reinforcing fillers, pigments, plasticizers, lubricants, antioxidants and curatives. Vacuum is utilized to de-volatile low boilers.
APorous has supplied color concentrate for packaging cast film extrusion, semi-compatible polymer-silica blends for blown film application and specialty polymer-glass blends for injection molding parts.
