Unitex Chemical Corporation introduces a new flame retardant to its product line. Uniplex FRX 44-94S is a non-halogen flame retardant.
Unitex Chemical Corporation introduces new formulation data for its Uniplex FRP-45, a halogen flame retardant plasticizer.

Uniplex FRP-45
Halogen Flame Retardant Plasticizer
Plenum PVC Wire and Cable

Uniplex FRP-45 provides many unique advantages to compounders of PVC wire and cable insulation. These include high flame retardant efficiency versus phosphate-based plasticizers, excellent thermal stability with low volatility, good plasticizing ability as a primary plasticizer, compatibility with all primary plasticizers, and good insulative properties.

Uniplex FRX 44-94S
A non-halogen flame retardant, recently added to the product palette of Unitex Chemical Corporation. This material is useful in flame retarding TPE’s, TPU’s, and various polyolefinic blends (EVA, LPDE, HDPE, and PP).

A few compounding tips for using Uniplex FRX 44-94S:

High tinting strength

Compound materials at of below 200° C

White parts are readily achieved by adding TiO₂

Standard color additives cause no difficulties

Good dispersion is essential, noting that high shear increases heat input

Use a silane coupling agent (0.25%) like OSi Specialties’ A-174 to aid dispersion

Proper devolatization during compounded is recommended

Loss of flame retardant efficiency is observed with the addition of Zinc Borate

POLYMER	STABILIZER	PROCESSING AID
