Santicizer® 148

• An active fire suppressant replacing other plasticizers which may act as fuels
• Compatibility in many polymer systems offers versatility
• Reduces smoke emissions during combustion
• Fast-fusing plasticizer in PVC systems to boost throughput
• Non-halogenated to avoid regulation and adverse perception
• Low volatility to maintain plasticizer presence during heat or vacuum processing

Valtris offers a family of non-halogenated, phosphate ester, fire retardant plasticizers that formulators can utilize to add specific performance benefits to products in order to meet smoke and flame testing requirements for their applications. These products offer the dual benefits of fire retardant chemical interactions, and the replacement of traditional plasticizers which act as fuels.

Santicizer®148 helps to suppress smoke during combustion of materials it is used in. Santicizer®148’s non-halogen nature avoids adverse perceptions of halogenated fire retardants. In PVC, Santicizer® 148 acts as a high solvating plasticizer, offering permanence, faster fusion and high plasticizing efficiency. Santicizer® 148, all with lower volatility than Santicizer® 141 to help plasticizer retention during processing.

Santicizer® Benzyl Esters as seal swell additives

In crankcase oils, transmission oils and hydraulic fluids the lubricant is in contact with the seal. Those seals can be made of different elastomers. The generally used elastomers are:

• nitrile butadiene rubber (NBR)
• acrylic
• silicone
• fluorinated

While aging, these elastomers tend to become harder (even brittle), tend to shrink and they tend to lose their elastomeric properties (as elongation). When this aging goes along with higher temperatures, as in automotive crankcase oils, this process is even accelerated.

The loss of those elastomeric properties in an engine can be the cause of leaks and thus loss of oil. But in order not to lose the properties of the elastomers and thus prevent leakage some polar additives have to be introduced. Those have to be as compatible as possible with the different elastomers. Alkyl benzyl esters, Santicizer® 261A, Santicizer® 278, Santicizer® Platinum P-1400 & P-1700, are good compatibilizers at a low dosage of 1 to 4 wt% for different type of elastomers. In the volume change aging test according the norm CEC-L-39-T-96 the addition of a seal swell additive as a benzyl ester is necessary to avoid shrinkage of the seal when put in a pure poly alpha olefin.

Santicizer® Phosphate Estes as anti-wear additives:

In general lubrication applications as hydraulic fluids and gearboxes and in metal cutting and forming lubricants anti-wear additives are used. Santicizer® 148, which is a non-classified alkyl aryl phosphate ester, is an excellent anti wear additive

Santicizer® 148 is an excellent plasticizer for low smoke and flame retarded flooring applications. Hereunder an example on how this plasticizer can be used in this application.
