Xencast PX30 Soft Flexible Polyurethane Resin

Xencast® PX30 is a soft flexible 30 Shore A polyurethane (PU) rubber with superior tear strength and resilience. It is ideal for casting soft grips, handles, tablet protection, gaskets and seals.

PX30 cures to a translucent amber appearance but can be pigmented to any colour. Degassing is not necessary but will improve performance.

Sold as a kit (Part A and Part B). Available to buy online in 1kg, 4kg and 10kg kits.

Xencast® PX30 is an industry leading flexible polyurethane rubber casting resin which cures to a very soft 30 Shore A hardness whilst retaining excellent tear strength and resilience. Xencast® PX30 is ideal for product applications requiring a very flexible, tactile material including soft-grip handles and rests or articulated components. PX30 can also be used to produce durable, flexible moulds for concrete casting.

Utilising the latest polymer technology, Xencast® PX30 is able to create flexible PU rubber parts with superior tear strength, abrasion and wear resistance and chemical tolerance.

PX30's highly translucent formulation means that it accepts pigments very well resulting in strong vibrant colours from reduced pigment concentrations. This translucency also makes it possible to use translucent tinting pigments to produce semi-transparent coloured castings which can even be illuminated.

Typical Uses

  • Soft grips and handles
  • Phone and tablet protectors
  • Flexible gators
  • Soft gaskets and seals

In conjunction with a suitable mould, Xencast® PX30 can be used to produce soft, flexible components like grips, handles, phone and tablet protectors and shock mountings.Xencast® PX30's abrasion resistance, tear strength and resilience also make it suitable for producing moulds for concrete casting.

Advantages

  • Very soft and flexible (30 Shore A).
  • Excellent abrasion resistance.
  • High tear strength.
  • Dimensional accuracy and fine detail reproduction.
  • Easily pigmented (translucent).
  • Low viscosity.
  • Easy 1:1 mix ratio.

Compatibility Information - Dos and Don'ts

Although by no means an exhaustive list, the mould materials, pigments and additives listed below have all been tested and are known to work well with Xencast® PX30.

Please download the technical datasheet for full details.

  • Compatible Moulds
  • Condensation/tin cure RTV silicone rubber
  • Addition/platinum cure RTV silicone rubber
  • Polypropylene and polyethylene mould 'trays'
  • Compatible Pigments
  • Polyurethane Colour Pigment (for vivid opaque colours)
  • Translucent Tinting Pigment (for less vivid opaque colours)
  • Compatible Fillers
  • Filler powders are not recommended

Xencast® PX30 should not be cast into latex rubber moulds. It should not be cast in contact with moisture or moisture harbouring materials such as wood.

Key Processing Information

  • Ease of Use
  • Suitable for professional and hobby use (follow SDS advice).
  • Odour
  • PX30 is almost odourless.
  • Appearance
  • PX30 is a translucent light amber colour.
  • Safety Precautions
  • Wear gloves and goggles and work in a well ventilated area. Always read the SDS before use.
  • Ambient Conditions
  • Can be used from 10 to 30°C although pot-life and cure time will be affected significantly. For small or thin-section castings an ambient of 20-25°C is required.
  • Degassing
  • Although not essential, vacuum degassing PX30 will eliminate air bubbles and ensure maximum tear resistance.
  • Mix Ratio
  • Mix 'Part A and 'Part B' 1:1 by weight. Use digital scales.
  • Mixing
  • Mix thoroughly by hand for at around 2-3 minutes.
  • Pot-Life
  • 25 minutes. Be sure to pour your casting(s) before this time.
  • Thin Sections
  • Thin sections will cure more slowly than thick sections. Make sure you allow enough time for thin sections to cure.
  • Cure Time/Demould
  • Larger castings will heat up more and cure quicker than small castings. Typical demould time is 24hrs at 25°C however full cure will not be reached for a further 7 days.
  • Shelf Life
  • The shelf life is 6 months from date of manufacture.
  • Pigments and Fillers
  • Pigment using polyurethane colour pigments or translucent tinting pigments.

You can certainly use this resin without degassing however we do recommend degassing to ensure maximum performance of the finished product by removing all traces of air. Bubbles can form weak points in the casting which promote tearing and ultimately early failure.

Due to the short pot life, if you do choose to degas the resin then we would recommend a degassing system that uses a high capacity pump so that there is enough time to degas within the resins pot-life. Our Professional Vacuum Degassing System - EC20-1 Vacuum Pump is the ideal one stop solution for degassing highly reactive resins with short pot-lives.

Glass Bubbles can be added to most resins to reduce the density of the cured material. However, bear in mind that they will reduce the clarity of the GlassCast resin, making it more of a translucent 'milky' appearance rather than transparent.

Assuming your skateboard wheels are perfect cylinders then the volume is quite easy to calculate using the formula Πr²h which in your case r = 25mm and h = 30mm giving a volume of 58.9 cm³. For Example, the density of PX90 is fractionally over 1g/cm³ which means you need 58.9g of resin per wheel or 235.62g for a set of 4. However check the density of the specific resin you are using in all cases so you multiply by the right figure to get an accurate weight.

However, most skateboard wheels have cut outs or hollows so the reality is you will use less resin. Calculating the volume in that case is a little more complicated as you need to calculate the volume of the cut outs then take it from the figures above to give the actual volume.

...the shore should be around 70 ish. Also, how well does it bond to metal, and can I treat the metal with a product to increase the adhesion?



Most commonly motor mounts (engine bushes) are made using something more like an 80 or 90 shore resin. In fact our PX90 has been used by a number of customers to create engine mounts.



If you're confident that you do need a 70 shore for your application then our closest shore hardness would be our PX60 but my opinion is that this would be too soft for most typical engine mount applications.



As for the bond to metal, we don't really have, and you shouldn't really need, an adhesion promoter for PU to aluminium - they should bond well. As usual, just make sure the surface is clean, completely grease-free (using acetone) and lightly keyed (using abrasive paper).

Xencast PX30 has a shelf life of 6 months from date of manufacture.

PX30 cures translucent amber. However, un-pigmented PX30 (along with the other PX series flexible PUs) is quite susceptible to UV light and it will go from a light translucent amber to a darker translucent amber quite quickly (within a few months) if exposed to light so if the colour/appearance is important do bear this in mind.

No, this resin cannot be described as hypoallergenic.
