Compounds with Required VSP

As per ISI standards – the unique formula of Silvin CPVC Compound reaches to VSP - 110°C and all other processing parameters of ISI standards. Our commitment is to give you the best final products made with Silvin CPVC Compound compounds.


Excellent Thermal Stability for wide processing window

Silvin CPVC Compound compound has higher DTS (Dynamic Thermal Stability), which allows you more processing time (of approx 21 mnts) against increasing heat generation in the machine. This helps you manage quality production.

“Silvin CPVC Compound” Industrial Molding compounds are commonly used for :

    Pipe fittings for industrial and potable water applications
    Valves and flanges Pump housings and impellers
    Filter bodies and parts Scrubbing tower packing and parts
    Parts which require fire resistance and low smoke generation
    Parts which require impact and gloss retention after weathering exposure

Silvin CPVC Compound customizes the grade
suitable for your machines at the
highest world standards


CPVC requires specific processing parameters in order to achieve ISI standard quality. If an operational plant is not conducive for quality output; Basil Prompt provide required alteration, guidance, training and develop customized compound formula for your existing machinery.

A special blend formula that combines Best of the both Worlds

Qualities of the costly imports
At your doorstep, at local cost

With localised technical support

CPVC products manufacturing is a difficult proposition. It requires 100% matching of material quality with production processes. Final output may suffer due to 50-50 % chances of difficulties arising in processing and materials. When you are dealing with us using Silvin CPVC Compound, we guide you and provide support on machines, molds, processing parameters, operational training etc.
