Based on polymer extrusion process technology, polymer rheology and supercritical physical micro foaming technology as the forerunner, Cowell Extrusion develops, designs and manufactures all kinds of new polymer foaming processing equipment and applies them in various fields.
From the mature and stable production line of CO2 foamed XPS sheet, to the fully bio-degradable production line of PLA foamed sheet, from the EPP/EPE micro bead foamed extrusion line to the production line of PET foamed sheet, Cowell Extrusion provides a full solutions.
Accurate measurement and injection of supercritical CO2 is one of the key injection processes for physical foaming.It involves not only accurate temperature control, pressure control, mass flow control but also the balance of the parameters of the production process.Because the operation range of supercritical CO2 foaming is very narrow, accurate measurement and injection play a crucial role in the successful use of supercritical CO2 foaming.Based on the physical characteristics of supercritical CO2, Cowell Extrusion has designed an injection system that ensures the supercritical CO2 can be accurately measured and stably injected.
Cowell Extrusion can provide the most mature supercritical CO2 injection system solutions in China, covering high and low CO2 injection process kits, and can provide customized solutions according to the actual needs.

XPE is is a kind of chemical cross-link PE foam with closed hole structure. It is made by LDPE compounding with coupling agent and foaming agent with continuous high temperature foaming. Compare to EPE, which is a physical foaming product, the tensile strength is higher, the foam hole is smaller. It is the ideal choice for automotive, air conditioner heat insulation. And it is widely used for sports facilities in recent years, such as surfboard, moisture-proof pad, yoga made,etc.
As is known to us all, the plastic pollution is getting more and more serious all around the world. For the plastic dish plates, the whole world has more than 4 million consumptions, most of which is non-biodegradable. In order to make our earth more green, COWELL has made his own contribution, we have develop the CO2 super-critical PLA foam extrusion line which can minimize the plastic pollution.
PET foam board is low density, high strength, low water absorption, good performance in soundproof and heat insulation. As a structural foam material, the strength and stiffness will be greatly increased while the density keeps the same. It is widely used in wind power, rail transportation, boat, and Aerospace material.
Cowell Extrusion is professional supplier of R&D, manufacturing of polymer processing equipments.
