Product Description

Expancel microspheres

Product Description:

Expander is a new special additive. It also named microsphere foaming agent . it is a kind of core-shell structure.The shell is a thermoplastic acrylic resin polymer and the core is a spherical plastic particle composed of alkanegases.The diameter is generally 10-45 microns. After heating, the volume can rapidly expand to tens of timesthan its own,thus achieving the effect of foaming. The foaming temperature ranges from 75 -260 C.

Technical index
Appearance: white powder
Particle size 5-30um
Initial foaming temperature (c) 70-180
Maximum foaming temperature (c) 185-195

Performance:

1. 1.Good thermal mechanical properties.
2. Excellent elasticity: Thermoplastic shell has excellent pressure resistance, the surface can withstand 300 kg/square centimeter pressure, good resilience can withstand repeated cyclic pressure/pressure relief without rupture.
3. Excellent foaming performance: can achieve the original 20-70 times of independent foaming effect,foaming is stilla complete closed body, with the traditional chemical foaming agent can not match the foaming effect.
4. Environmental protection performance: Polymer microspheres are non-toxic and pollution- free,and can be used as environmentally friendly foaming agent in high-end products and high value-added products.

Application

Expandable microcapsule Mainly used in thermoplastic elastic foamed soles, such as TPU/TPE(SEBS/SBS)/TPR.Waterborne paint, waterborne printing pulp, waterborne wallp, etc.
Applied to PVC air-blown slippers, it has the following advantages: small addition, can give PVC air-blown slippers ultra-light weight, small density, make the product foam fine and uniform, the product after stereotyping skin smooth and bright color, bright, non-matte effect (better than other types of expanders),soft, comfortable,small shrinkage.

Usage method

Easy to use, adding in the formula, mixing and stirring evenly, control the temperature can be good,do notneed to adjust the original process, the amount of addition according to the industry and the effect achievedis generally 0.5-1.5%.
