Product Application Note

Unitex Chemical Corporation announces the commercial development of three new benzoate esters in the expansion of the current benzoate ester line. These materials are useful in a number of synthetic resin formulations, especially where non-phthalate plasticizers are required. The new products are:

Uniplex 354, Uniplex 408, Uniplex 446

UNIPLEX 354 (1,3-Pentanediol, 2,2,4-Trimethyl-, 1,3-Dibenzoate, CAS No. 68052-23-3): This diester plasticizer is compatible with a wide range of synthetic resins. It is suggested as a resin plasticizer/modifier in the formulation of specialty coatings, adhesives, and PVC plastisols.

UNIPLEX 408 (Polyethylene Glycol Dibenzoate, CAS No.9004-86-8): This liquid plasticizer has low volatility and is compatible with several polymers such as PVC, PVA, acrylics, phenolformaldehyde and some alkyds. The low volatility and polar nature of this product make it useful in formulations containing thermoset polymers, such as phenolic resins. Uniplex 408 provides improvement in flexibility, flex strength, and heat distortion values without sacrificing electrical properties.

UNIPLEX 446 (Trimethylol Propane Tribenzoate, CAS No. 54547-34-1): This solid plasticizer (melting point 84°C) is useful in a numbers of plastics and adhesives. The product is useful in food packaging materials, both films and adhesives. Uniplex 446 is also a useful additive as a toner binder, powder coatings, and specialty photographics.

Unitex Chemical is a growing specialty chemical corporation focused on manufacturing high performance plasticizers and flame retardants. We serve a variety of applications such as the adhesives, sealants, cosmetics, coatings, and thermoplastics and thermoset markets.

Product Application Note

This product application note reviews the utility of various products manufactured by Unitex Chemical Corporation. These materials are useful in a number of synthetic resin formulations, especially where non-phthalate plasticizers are required. The products are:

Uniplex 400, Uniplex 512, Uniplex 988

UNIPLEX 400 (Polypropylene Glycol Dibenzoate, CAS No. 72245-46-6): This low volatility, moderately solvating diester plasticizer is compatible with a wide range of synthetic resins. It was designed to be used in applications requiring a plasticizer lower in volatility than diethylene glycol or dipropylene glycol dibenzoates. Uniplex 400 is an efficient, cost/performance alternative to the high alkyl benzyl phthalates.

UNIPLEX 512 (Neopentyl Glycol Dibenzoate, CAS No.4196-89-8): This solid plasticizer (melting point 49°C) has low volatility and is compatible with several polymers. This product is especially useful as a cleaner for adhesives.

UNIPLEX 988 (Dipropylene Glycol Dibenzoate, CAS No. 27138-31-4): This liquid plasticizer is useful in a numbers of plastics and adhesives. The low hydroxyl version is recommended as a plasticizer for cast urethane applications that require a minimum cure interference and maximum in compatibility. The excellent degree of compatibility in cast urethane systems allows use at high levels to achieve durometer readings ranging as low as 20-25 Shore A hardness for graphic arts applications.

Product Application Note

This product application note reviews the utility of various products manufactured by Unitex Chemical Corporation. These materials are useful in a number of synthetic resin formulations. This product application note is focused on the flame retardants manufactured by Unitex Chemical Corporation. The products are:

Uniplex FRP-45, Uniplex BAP-370, Uniplex FRP-64

UNIPLEX FRP-45 (Bis (2-Ethylhexyl) Tetrabromophthalate, CAS No. 26040-51-7): This low volatility, flame retardant plasticizer provides excellent plasticizing and flame retardant properties in formulations using PVC, Neoprene, and EPDM. This product is useful for wire and cable, conveyor belts, and various industrial PVC applications.

UNIPLEX BAP-370 (Tris (Tribromoneopentyl) Phosphate, CAS No.19186-97-1): This melt processable, solid flame retardant (melting point 181°C) has low volatility and is compatible with polypropylene (molding and fiber applications), HIPS and EPS (no "leopard spots" due to decomposition like HBCD), and PVC (a low smoke additive). This product has excellent chemical resistance and light stability (does not react with HALS light stabilizers). 5% loading will achieve a UL-94 V-2 rating.

UNIPLEX FRP-64 (Polydibromophenylene Oxide, CAS No.69882-11-7): This melt processable, solid flame retardant (melting point 210°C) is useful in thermoplastic polyester and nylon (both unfilled and glass-filled). It has excellent mechanical and thermal stability properties with low shrinkage rates. Loading levels for UL-94 V-0 applications are approximately 15%.

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
LDPE, HDPE, EVA	0.25% Cyanox 2777	1% Stearic acid or 0.25% A-174 Silane
PP, Unfilled or Glass-filled	0.25% Irganox 1010	0.25% A-174 Silane
