Basic Types of "POLY FLEX™ / AKORROS®" Rubber linings.
|  Hard Ebonite | |
|  Di FLEX a) Soft + Hard b) Hard + Soft | |
|  Chloroprene (CR) | |
|  Hypalon ® (CSPE) | |
|  Nitrile (NBR) |
| PRP offers many other high tech "POLY FLEX™ / AKORROS ®" linings to suit special service
conditions to meet individual requirements. |
Application and curing of the Linings
Following methods are being used for curing of rubber linings :
| a) Autoclave methods | Under pressure of steam Rubber lining is cured (vulcanised) |
| b) Open Steam | Under Atmospheric Pressure Rubber lining is cured |
| c) R.T.Curing Method | In case of very long, Large Tank/Equipment rubber lining is cured at Room Temperature by accelerated chemicals which takes several days/weeks to cure and it can be cured faster at elevated temperature. |
In certain cases equipment itself is made as Autoclave for curing purpose.
Bonding Adhesive to bond uncured rubber linings.
| With our experience of more than three decades, we have developed varieties of bonding adhesives with different combinations to suit varieties of service conditions like, |
| a) High pressure & impact b) Vaccum c) High Temperature d) High frequency Thermal expansion contraction of equipment. e) High abrasion, erosion& velocity. |
Cold Bonding Adhesive
| For Special conditions pre-cured "POLY FLEX™ / AKORROS ®" linings can be applied to different substrates like Concrete, M.S., S.S. etc. and after applications no vulcanisation is required as they are self curing at R.T. |
