The invention discloses a formula for a PVC foaming sheet. The formula comprises the following components by weight: 100 parts of PVC resin, 15 to 50 parts of calcium carbonate, 10 to 40 parts of talcum powder, 25 to 70 parts of aluminum hydroxide, 1 part to 10 parts of a heat stabilizer, 4 to 20 parts of a foaming agent, 2 to 10 parts of a foaming conditioning agent, 1 part to 10 parts of a.【Get Price】
Recently, PVC has come under scrutiny because of potential health and safety concerns but many of these claims are misdirected because in actuality it is the various other materials which have been added to PVC formulations to be able to process for a particular use that are the problem.【Get Price】
Polyurethane foam is sprayed over the surface of the prepared substrate. The polyurethane foam is coated with acrylic, urethane, or silicone rubber coatings. Roofing granules may be broadcast into the wet coating to improve weatherability. Uncoated foam “rusts” (forms a brown dusty layer).【Get Price】
PVC foams came into use as core materials in the 70’s. As sandwich structures in marine applications began to be optimized, a need for a low-density, consistent, moisture resistant core material was realized. Formulations were refined over the years and the characteristics of PVC foams fit the needs of the marine industry well.【Get Price】
PVC-U formulations have low flammability due to the chlorine content. The addition of plasticiser in PVC-P formulations necessitates the use of flame retardant and smoke suppressant additives. These additives are known as functional fillers and a correct balance is necessary to achieve all the end-use specification requirements.【Get Price】

A typical foam formulation contains PVC resin; a heat stabilizer such as a Thermolite® organotin stabilizer available from Elf Atochem, a Mark 1925 tin stabilizer available from Witco or a lead stabilizer such as a tribasic lead sulfate, a dibasic lead stearate or a dibasic lead phosphate; an impact modifier such as a Metablen® C223 or.【Get Price】
A majority of Stabilisers contain metal elements which react with HCl and inhibit further degradation. They are Metal Salts, Soaps or Complexes. Stabilisation of PVC is a vast subject and these are the second most important ingredient after Plasticisers in a Flexible PVC formulation. Some of the most important families are:【Get Price】
