Types of Organic Peroxides to meet the demand
Perodox B - DTBP CAS 110-05-4
Polymerization of acrylate and methacrylate: Within the temperature range of 130-175 ℃,
it can be used as an initiator for solution polymerization or copolymerization of acrylate and methacrylate, especially in the production of coatings. It can also be used as an initiator for bulk and suspension polymerization or copolymerization of acrylate and methacrylate.
Perodox L75 - BPO75 CAS 94-36-0
BPO75 is an initiator (powder formulation with 75% benzoyl peroxide and 25% water) used for curing unsaturated polyester, vinyl ester and acrylic thermoset resins at ambient or slightly elevated temperatures. It is often used in conjuction with tertiary amine accelerators at ambient conditions. Typical uses include cast polymer, panels, chemical anchors and mine bolts and RTM.
Perodox C - TBPB CAS 614-45-9
In the temperature range of 100-170°C, TBPB can be used as an initiator for the solution polymerization or copolymerization of acrylate and methacrylate, especially for the production of coatings. TBPB can also be used as initiator for bulk and suspension polymerization or copolymerization of acrylate and methacrylate.
Perodox LUNA - LPO CAS 105-74-8
LPO is a widely used initiator for the suspension and mass polymerization of vinyl chloride between 60°C and 80°C. In many cases LPO is combined with a more active initiator, such as a peroxydicarbonate to increase reactor efficiency. LPO is used as an initiator for the high pressure polymerization of ethylene, but because of its poor solubility in most aliphatics, it is in many cases replaced by other peroxides such as Di(3,5,5-trimethylhexanoyl) peroxide (TMHP). The advantage of LPO is the possibility of storing at ambient temperature. LPO is also used as an initiator for the polymerization of methylmethacrylate at 60-90°C. LPO is often applied as a replacement for 2,2'-Azobis(isobutyronitril) (AIBN).
Perodox 14 - BIPB CAS 25155-25-3
BIPB is a bifunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Rubber compounds containing BIPB have excellent scorch safety, and under certain conditions one step mixing is possible. Safe processing temperature: 135°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 175°C (rheometer t90 about 12 min.).
Perodox 21 - TBPEH CAS 3006-82-4
TBPEH is an efficient initiator for the production of Low Density Polyethylene (LDPE). It is used both for tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range. In suspension polymerization processes, TBPEH can be used for the polymerization of styrene at approximately 90°C. TBPEH has an activity comparable with Dibenzoyl peroxide (BPO75). Typically, TBPEH is used in combination with initiators such as tert-Butyl peroxybenzoate (TBPB) and tert-Butylperoxy 2 ethylhexyl carbonate (TBEC).
Perodox M50 - MEKP CAS 1338-23-4
MEKP is a methyl ethyl ketone peroxide formulation for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. MEKP is suitable for the cure of both thin and thick sections in one particular product.
Perodox 101 - BPDH CAS 78-63-7
BPDY is a bifunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Safe processing temperature: 145°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 185°C (rheometer t90 about 12 min.)
Perodox K - CHP CAS 80-15-9
For Polymer production andPoly(meth)acrylics: CHP may be used for various polymerization reactions. It can be used in emulsion, solution and bulk polymerizations. In emulsion processes, CHP may be activated by organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature or lower.When no accelerators are used, effective polymerization can be obtained in the
temperature range of 50-200°C. For example, styrene and methyl methacrylate can be polymerized in bulk in the temperature range of 60-100°C using CHP. CHP may also be used for emulsion polymerization of various vinyl monomers. In this case CHP may be used in combination with reducing agents to achieve
reproducible results at low temperatures. For Thermoset: CHP may be used as an initiator for the room temperature cure of promoted unsaturated polyester and vinyl ester resins, and elevated temperature cure of non-promoted resins.
