Effective content:
- It is a composite foaming agent with good dispersion. Non-toxic, odorless and pollution-free. Microspheres expand to form foam after being heated. They have good foaming ratio and resilience for soft rubber foam products and are widely used in various thermoplastic elastomers. The microspheres expand and foam under high temperature, and the pores are uniform and fine. The product has excellent resilience and a large amount of gas. Excellent dispersion effect.
Applicable process: Injection molding/extrusion and other processes, mix the resin and foaming agent masterbatch evenly and then process directly
Application fields:, B, (B,B),,,, (), ,. Foam sealing strips for shoe soles (for automobiles, etc.) and other packaging areas that require foaming.
Recommended dosage: injection molding to 3, extrusion to 3.
Process requirements:
.Injection molding
In most cases - the foaming agent can be used in general injection molding equipment. It is best to use a nozzle with a needle valve that allows filling of the model by expansion.
In terms of products: eliminate dents, remove warpage, improve dimensional stability, reduce weight, and increase the resilience of thermoplastic elastomers.
In terms of technology: high injection rate and injection pressure, lower injection pressure and reduced mold locking force, reduced back pressure, reduced cooling time and increased productivity.
?
.Extrusion molding
- Foaming agent can be used on most extrusion equipment. The screw length-to-diameter ratio is optimal for dispersion. Sufficient melting temperature helps to completely decompose the foaming agent. Closing the vent hole can avoid gas loss. Using a low-shear screw and high rotation speed process can minimize the impact on the foaming agent. of destruction.
In terms of products: it can make the product into a micro-bubble structure to reduce weight and improve thermal insulation
Application: pipe edge strip extrusion (wire casing, oil pipe, window edge strip) extrusion of thick plate
br/> Packaging:/barrel, cardboard barrel packaging.
