Applications |
|
|
|
|
|
1) The initiator of
unsaturated polyester resin |
|
|
|
|
Alkenox P-100 has low decomposing
temp.(44¡É). |
|
|
|
|
It is suitable for pultrusion mold,
continuous laminating and large scale mold. Especially large scale molding,
heating furnace is needed to get a high temperature. |
|
|
Alkenox P-100 which has low decomposing
temp is suitable for that cases. |
|
|
|
Alkenox P-100 is also used with other
curing agent such as BPO(Benzoyl peroxide), TBPB(t-butyl-perbenzoate) and
other metal salt accelerators. In that case, we can expect a improved
properties after curing. |
|
|
|
|
|
|
|
|
2)
Polymerization initiator of VCM(Vinyl Chloride Monomer) |
|
|
|
|
Alkenox P-100 is used for polymerization
initiator of VCM which is the monomer of PVC at 40~70¡É. |
|
|
3)
Polymerization initiator of other monomer |
|
|
|
|
Alkenox P-100 is used
as initiator of homopolymerization & copolymerization of acrylates,
methacrylate and vinylidene fluoride monomer. |

|
2)
Storage |
|
|
|
|
|
Alkenox P-100 is quite
active peroxide. However handling it at room temperature is possible as it¡¯s
storage stability at room temperature is a rather high so it is possible to
handle at room temperature. |
|
|
But it can be decomposed at above 25¡É, so it must be stored under 20¡É and kept away from direct
sunlight |
|
|
3) First Aid |
|
|
|
|
|
Skin contact cause a
hazard like other peroxides, so appropriate protection is needed. During
working, protective clothes and protective hand cream is needed. |
|
|
¨ç Eye Contact : Immediately flush eyes with plenty of water |
|
|
|
|
Get
medical attention immediately |
|
|
|
|
¨è Skin Contact : Immediately flush skin with plenty of soap |
|
|
|
|
and
water. Get medical attention immediately. |
|
|
|
|
¨é Ingestion : Not to vomit. Get medical attention. |
