Polymer Additives

Textile Dyeing & Highly Reflective Material:

• SCF CO2 infusion of dye to synthetic fibers

• SCF CO2 infusion of Si containing additive to PEEK

• Rapid CO2 depressurization leaves additives behind

Textile Sizing:

• Coating a smooth PVA film on fibers to add strength before weaving.

• Adjustment of conditions allows control of penetration.

• Fibers do not stick together after drawing through SCF.
