Customised Polyurethane Parts and Drill and Blast Solutions

PR Polymers (PRP) manufactures and supplies mineral processing products, custom-made polyurethane parts, drilling components and air decking / stemming solutions for the global mining industry.

We also develop additional high-quality products so they are suitable for both applications worldwide and adverse Australian climatic conditions.

Over more than two decades, PRP has grown to become a reputable industry leader of high-quality and performance products.

PR Polymers develops drill and blast components for the mining industry.
Our engineering capabilities allow us to manufacture customised polyurethane components.
Drill hole savers can significantly reduce the levels of regrind incurred and respirable dust on-site.
KOOLKAP® Down-Under bags are suitable for air decking or top-hole applications
PR Polymers’ customised deflector sheets ensure cuttings are deflected well away from the hole.
We offer consumables on retail and wholesale such as abrasive wheels, poly chains, and detonating cord cutters.

Self-inflating down-under bags for sealing blast holes

Our patented, non-hydrofluorocarbons (HFC) KOOLKAP® Down-Under bags are a safe and environmentally friendly solution for air decking or top-hole applications.

Designed to deliver zero failure, there is no waste disposal or user risk with our full range of bags.

KOOLKAP Down-Under bags can also be customised to your needs and we will trial, test and provide solutions to deliver a tailor-made product. We offer raw materials in different combinations to achieve the specified grip and load times while retaining a high-quality product.

Our new push actuator cap ensures a positive large thumb press, which is suitable when wearing gloves with a positive clip-in mechanism, capable of activating the bag to full inflation first time, every time.

Self-contained decoupled charges

KOOLKAP Bikini Bags (KBB) are self-contained decoupled charges for larger diameter blast holes of open-cut mining.

KBBs can hold up to 100 litres and the booster/primer can be placed directly in the product or in the external pouch of the bag. They also prevent dead pressing in blast columns of more than 70m and can be placed precisely adjacent to hard bands in wet holes.

Custom-built deflector sheets

PRP’s customised deflector sheet is specifically engineered with high-rebound qualities to ensure cuttings are deflected well away from the hole, reducing wasteful and expensive redrilling from fallback.

As a result, you will have less airborne respiratory dust and larger chips in your pile, and your cuttings pile then can be used as stemming, reducing your drilling cost per metre by up to 50%.

Drill hole savers

We offer a range of drill hole savers and manufacture rotor-moulded and injection-moulded cones to keep drill hole collars clean and reduce fallback and groundwater leakage.

The cones are highly visible and UV stable, lightweight and easily stackable.

Available in a wide range of different sizes and colours, drill hole savers can significantly reduce the amounts of regrind incurred and respirable dust on-site.

PRP offers drill and blast consumables on retail and wholesale to make drilling projects faster, more efficient, clean and safe.
