Precipitated silica and silica gel
Keeping track with latest market development we, Hir Primak Enterprise, are actively engaged in importing, exporting and supplying Silica gel which is an amorphous form of silicon dioxide, which is synthetically produced in the form of hard irregular granules or beads. A micro porous structure of interlocking cavities gives a very high surface area (800 square meters per gram). It is this structure that makes silica gel a high capacity desiccant. Water molecules adhere to the gels surface because it exhibits a lower vapour pressure than the surrounding air. Silica gel physically adsorbs water vapour into its internal pores. Standard white silica gel is referred to as being non-indicating. As it adsorbs moisture it remains physically unchanged. Non-indicating silica gel is both cheap and effective, available loose in bulk packs or packed in sachets. Indicating silica gels are colored gels whose colour changes as they absorb moisture.
...morePolyethylene Terephthalate
We, Hir Primak Enterprise, are actively engaged in importing, exporting and supplying Polyethylene terephthalate(PET) which is a general purpose plastic produced by the polymerization of ethylene glycol and terephthalic acid. Ethylene glycol is a colourless liquid obtained from ethylene, and terephthalic acid is a crystalline solid obtained from xylene. Polyethylene terephthalate (PETE or PET) is the most commonly used thermoplastic polymer in the world and is better known in the textile industry by the trade name “polyester.” It is used as an effective moisture barrier with wide applicability in bottling and packaging, and as an engineering plastic when it is combined with other materials like glass fiber or carbon nanotubes to significantly increase the material’s strength.
