Applications:

PLASPEROX TBP – 98 is an active source of free radicals for high temperature (100 – 150⁰ C) polymerization of vinyl, acrylic, allyl and olefin monomers. 

PLASPEROX TBP – 98 is particularly suitable for heat – curing of unsaturated resins.  It is commonly used when long shelf-life is required, as in sheet/dough moulding compounds (SMC/DMC).  The usage level is normally 1% - 1¹/₂% on the weight of the polyester resin, depending on the formulation and the curing conditions.  

The quality of surface finish on press moulded polyester parts depends on the exotherm produced during curing.  PLASPEROX TBP – 98 generally produces higher exotherms than other peroxides and so gives better surface finish on the mouldings.  Certain peroxides like benzoyl peroxide are predictable in their activity in the presence of some pigments which may inhibit the cure.  PLASPEROX TBP – 98 does not interact with any pigments. 

PLASPEROX TBP – 98 is also used as a cross-linking agent for natural and synthetic rubber, silicone rubbers and polyethylene. 

PLASPEROX TBP – 98 is used as a drying accelerator for paints and varnishes.  It is also used as a mild oxidizing agent in organic reactions. 

HANDLING & STORAGE :

PLASPEROX TBP - 98 is not explosive and is insensitive to shock or friction.  It is inflammable and on ignition burns with an intense smoky flame. 

PLASPEROX TBP – 98 must be considered as a fire hazard like any other inflammable organic solvents.  It should be kept away from all sources of heat such as radiators, steam pipes, fire and open flames.  Avoid contamination with heavy metals and their salts, particularly cobalt accelerators.  It should be stored in a cool place away from direct sunlight. 

PLASPEROX TBP – 98 must be stored in original container which must be vented occasionally to release any internal pressure. 

PACKING & TRANSPORT :

PLASPEROX TBP – 98 supplied in 50 kgs. polythene container is transported by road, rail or sea.  It is prohibited for despatch by air or postal service. 

WARNING :

PLASPEROX TBP – 98 is an oxidizing agent and care must be taken to avoid contact with skin, eyes and clothing.  In the event of contact with skin, wash off immediately with soap and water.  If it enters the eye,  immediate and prolonged irrigation with water.  A freshly prepared 5% solution of sodium ascorbate or bicarbonate or “OPTREX”  eye lotion should be given followed by prompt medical attention.
