POLYBIT POLYFOAM PIR-35 BA

Two component, polyisocyanurate block system

  • Injection/pouring grade
  • 35kg density PIR

Features and benefits

POLYFOAM PIR-35BA is an HCFC-blown & CFC free, polymeric M.D.I based system to produce rigid PIR foam.

Properties

Description

POLYBIT® POLYFOAM PIR-35BA is a two-component, Injection/pouring grade polyisocyanurate foam system developed for rigid PIR blocks, which has greatly increased resistance to burning and spread of flame. The composition of POLYFOAM PIR35BA, when subjected to fire, the outer surface forms a strong carbonaceous layer which retards further flame spread and is able to withstand temperature up to 140˚C. POLYFOAM PIR-35BA is an HCFC-blown & CFC free, polymeric M.D.I based system for producing rigid urethane foam with a nominal core density of 35kg/m³ by injection/Pouring process. Grades, adjusted in reactivity, are available for both cold and hot condition. Available Pack: 220KG/DRUM

How to use

How to use

Surface Preparation

Apply wax / releasing agent inside the mold

Mixing

Take required quantity of Polyol and MDI based on the calculstion of mold dimension and density that you want to attain. Mix it with help of stirrer and pour it inside the mold and close it with the lid. 

Curing

Demold the PU block and stack it aside for curing for atleast a period of 02 weeks before cutting. It is later cut in to desired shapes (pipe section or blocks) in CNC machine.
