Poly-Dispersion TRD-90
90% red lead oxide in an EPDM/EVA binder
Rhein Chemie Corporation
ï

Sp.gr. 4.58; orange slabs

Preferably used as an activator in acid resistant compounds. It considerably reduces the swelling of vulcanizates in water; is suitable as an oxidizing agent for the vulcanization of butyl rubber with p-quinone dioxime; can be used to improve the heat resistance in peroxide cured CPE compounds; is not recommended for use in thiadiazole cured CPE; filler in compounds for protective covering, because of the high absorption capacity to x-rays.


PLC(TAIC)72
72% triallyl isocyanurate 28% inert mineral carrier
Rhein Chemie Corporation
ï

Sp.gr. 1.31; off-white dustless powder form

Powdered liquid concentrates are free flowing dustless powder dispersions of liquid ingredients on an inert mineral carrier.


Rhenofit F
Specially treated fine CaO
Rhein Chemie Corporation
ï

Sp.gr. approx. 3.0; white powder

Cross-linking modifier and desiccant for the use in fluoroelastomers.


PLC(SR517)-72
72% SR517
Rhein Chemie Corporation
ï

Sp.gr. 1.26; free flowing dust suppressed powder on an inert carrier.

PLC(SR517)-72 is a replacement for other SR517 liquids sould be evaluated as a direct replacement on an active ingredient basis; the improved handling and reduced waste can reduce raw material requirements
