Climate Control and Heat Proofing Material for all type of structures

Sinicon PP

The company has several products to serve the need of consumers, one such product is Sinicon PP.

A heat proofing plaster and screed aggregate used for plastering and many other applications, derived out from unique volcanic glass, a large deposit of which is found at only one location in South Africa and nowhere else on earth. Its properties are similar to classical perlite but it differs in that the processed form is ideally suited for use with cementitious and other binders. It also has truly exceptional fireproofing properties.

The volcanic glass ore is crushed and passed through a series of specially developed processing equipments and through this patented process crushed grains are converted into a multitude of well sealed glass beads. It also alters the chemistry of the glass and results in a higher melting point. Under the microscope, each tough bead comprises a forth of glass-walled closed cells each enclosing a new vacuum. Expanded Sinicon PP is therefore best described as comprising millions of tiny sealed ”thermos flasks”, hence its absolutely unique and unrivalled insulating and fireproofing properties.

Advantage of the properties

Excellent thermal insulator

The thermal property of Sinicon PP is very low due to its low density and physical structure. The ‘k’ value of Sinicon PP in loose form and when mixed with binders are as follows:

When binders like cement added for plastering application, the K value will be as follows:

a)         Sinicon PP in loose state         :  0.05 W/m  C

b)         Sinicon PP : Cement 4.5 : 1 : 0.13 W/m  C

c)         Sinicon PP: Cement 3:1  :   0.15 W/m  C

Ultra lightweight

Density in the loose state is 100 kg/m3 and, when mixed with cement, practical concrete densities raging from 300 kg/m3 to 1000 kg/m3 can be achieved. The Sinicon PP concrete will therefore float on water.

The density at various Sinicon PP : Cement proportion follows:

Ratio 3:1                  :  770  kg/m3

Ratio 4.5:1       :          670 kg/m3

Ratio 6:1                  :  480 kg/m3

Ratio 10:1        :          360 kg/m3

Note : Sand + Cement (4:1) Mortar will have a density of approx. 2000 kg/m3.

Exceptional Fire Resistance

Notwithstanding the high melting temperature of 1250C Sinicon PP concrete can also maintain its structural integrity at high temperatures due to its thermal insulating property. The latter ensures a very high thermal gradient on the outer surface  during fire conditions resulting in very low temperatures immediately below the fire exposed surface. Indeed, even if the surface melts, it coalesces into molten glass beads which insulate and protect the interior.

Compatibility with Portland Cement and Other Binders

Unlike conventional perlite family products which is often friable and delicate with many fractured cells, Sinicon PP has a well-sealed tough structure. This prevents severe bead damage during mixing and facilitates low water absorption, hence proper curing of the cement.

Superior Strength

Ultra lightweight concretes are generally weak and, in the case of aerated concrete, are extremely vulnerable to total slump shortly after casting, especially if any vibration or disturbance is present. Sinicon PP concrete does not rely on air entertainment and can be cured under any conditions of variation. Once cured, the product exhibits surprising strength in comparison to other lightweight concretes. Strength varies with density but practical strengths in the range up to 23 MPa are quite achievable.

Adhesion (Spray or Plaster)

Sinicon PP, which when mixed with cement, can be plastered (without the use of additives) either with a trowel or by spray to most common surfaces with good adhesion. In the case of doubtful/smooth surfaces, a recognised cleaning procedure, followed by the application of bonding agent, i.e a plaster grip primer, is recommended. In this case, Sinicon PP plaster will even adhere to smooth steel.

Low Water Permeability

The Sinicon PP, when mixed with cement in the correct ratio, can be deemed to be completely watertight without the use of any additives (Ref. PCI Report). Substrate corrosion is therefore minimised.

Non-toxic Dust

No dust is healthy. Sinicon PP, due to its amorphous(non-crystalline) structure has however been demonstrated to be a very low risk dust.

Zero Smoke and Zero Fumes

Due to its inorganic structure “Sinicon PP” evolves zero smoke an zero fumes under fire conditions.

Amazing resistance to spalling

Under fire conditions and, more severely, under water quench conditions following extreme heat, (e.g. from a fire hose) conventional concrete will spall and lose its integrity. Sinicon PP exhibits no such tendency and, following a fire, the material generally need not be replaced.

No weather effect

No effect on the structure due to frequent changes in the weather i.e. switching of weather generally affects the conventional plaster and concrete, but has no effect on Sinicon PP plaster/screed. Substrate corrosion is therefore substantially reduced extending the life of the concrete structure.

Improved Acoustic Properties

Being a soft material with vaccum feature in the Sinicon PP it improves the acoustic properties of the building.
