Description

EXTRUDE FOAM WITH CO2: TURN-KEY solution concept: XPS insulation boards begin as a solid granule. The granules are fed into an extruder where they are melted and critical additives are mixed with the viscous fluid that is formed. Then, a blowing agent is injected to make the mixture foam able. Under carefully controlled heat and pressure conditions, the foam able mixture is forced through a die, at which time forming and shaping occurs. The rigid foam is then trimmed to the final product dimensions. Available specification of the foam board Thickness range - *0mm***0mm, variable with different formulation and also blowing agent. Width range - **0mm/***0mm, specified width could be required. Maximum capacity - up to ***0kg/hr. Blowing agent - optionally with CO2, HFC, butane etc. Base polymer - Polystyrene. Injection units for blowing agents Precise metering and injection units for CO2, HFC or butane could be specifically configured according to different requirement. Other liquid injection as added blowing agent could also be equipped.
