Endex4223™

Endothermic Chemical Foaming Agent and Process Aid

 

n  INTRODUCTION:

Endex 4233™ is a high efficiency pelletizedconcentrate, in a thermoplastic polymer carrier.

It is designed foruse in both commodity and engineering plastics, and may be dried with thepolymer if needed. It combines its endothermic properties, quality andefficiency, with versatility and cost-effectiveness.

 

Endex 4233™ endothermic chemical foamingagent utilizes innovative technology to produce superior quality foamedproducts. It generates very fine, closed-cell foams, which result in moldingsand extrusions of high quality.

 

Endex 4233™ Processing  Aid can be used in injection molding for cycletime reduction, im- proved polymer flow, reduced processing temperatures,improved weld line strength, and to eliminate molded-in stresses which causewarp and sinks.

 

n USAGES:

• Injection moldingfor cycle time reduction, sink marks, warp reduction, shrink control.

• Structural Foammolding (SFM). Gas Counter-pressure foam molding.

• Nitrogen SFM for finer cell structures andextra weight reduction.

• Gas Assist molding for extra weightreduction and sink elimination.

• Extrusion of Sheet,Film, and Profiles.

• Blow Molding,Rotational Molding.

 

n USE LEVELS:

Endex 4233™ uselevels will vary with the application, but the following guidelines can be usedas a starting point. Optimization for each application is recommended:

 

• Structural Foam Molding

n ADVANTAGES FOR PLASTIC PROCESSOR:

Endex 4233™ has many advantages for theplastics processor, including:

• Fine cell structure

• Shorter cycle times

• Faster extrusion

• Thick, smooth skins in SFM

• Fast degassing

• Fast painting and decorating

• No plate-out on molds

• Beryllium-copper compatible

• G.R.A.S. or FDA sanctioned ingredients

 

n PACKAGING:

Endex 4233™ is available in 50 lb cartons, or1000 lb boxes.
