Materials we use..
Multotec has developed a number of composite materials in response to specific demands for the properties of polyurethane coupled with those of other materials. The result is a range of exclusive materials that bring a new level of performance to the use of polyurethane elastomers.
Material Information:
Polyslip
Multotec developed Polyslip to bring an exceptionally low coefficient of friction to the outstanding properties of castable elastomeric polyurethane.
The latest Polyslip materials are based upon specially manufactured silicone additives that are homogeneously dispersed through the polyurethane elastomer to impart a reduced coefficient of friction, increased abrasion resistance and improved mechanical properties. Polyslip is manufactured in three base hardness materials and can be manufactured to finished sizes of up to 1550mm wide and 4200mm long. It can be supplied bonded to steel backing plates. Polyslip inhibits caking and clogging, reduces down time, reduces noise and protects against corrosion.
Polyslip 40
High wear resistance with very good impact properties. This is a 90 shore A / 40 shore D material. It has a high resistance to stress and good sliding properties. Polyslip 40 is an excellent general purpose material for use in ore conveying where 75mm minus lump is evident. Also recommended for slide plates, scrapers and wear pads.
Polyslip 50
This is a 95 shore A / 50 shore D material often supplied with a fire resistant anti-static additive for use where there is static build up from friction of product over the lined surface. Highly suitable for grain industry lining chutes, silos and bins.
Polyline
Polyline is a 70 shore A material specifically designed to supersede rubber linings in the 60-70 shore A range with significantly improved wear life. This material is designed to absorb impact and impart rebound to the material being transferred. It is designed to protect steel against impinging and sliding abrasion. Polyline is pliable and easily formed and can be used in conjunction with Polyslip to line a multitude of different components including chutes, bins, tanks, pipes and laggings.
Cerathane(TM)
Described as the material of the future, ceramic is one of the hardest of all natural substances known to man. Under extreme abrasive conditions there is virtually no material that can compete with its extreme hardness and wear resistant qualities. Ceramic componentry is very expensive when compared to other materials, and in order to bring a more cost-effective product to the market, Multotec developed a revolutionary product called Cerathane(TM), a unique combination of a special alumina ceramic and polyurethane.
Multotec overcame the traditional problems of effectively bonding the ceramic with the polyurethane by developing a unique manufacturing process. The result is a product that has shown an increase in life of up to 25 percent over traditional polyurethane products in wear resistant applications at a cost increase of around 10 percent over traditional polyurethanes, but at a substantial price reduction over conventional alumina ceramic products.
The percentage of ceramic in Cerathane(TM) can be varied for specific client applications so that the compound can be adapted to maximise the qualities of mechanical, chemical, thermal or electrical insulation properties and it can also be adapted to various sizes and shapes.
The performance characteristics of Cerathane(TM) allow it to be used in applications where other materials simply cannot be used satisfactorily. Generally where very high tear resistance and high load-bearing along with high abrasion resistance is required, Cerathane(TM) is a high performance cost effective solution. Given its ability to outperform standard polyurethanes, this longer life feature is of substantial benefit to mining and industrial applications where down time is a critical factor.
Cerathane(TM) componentry is lighter than comparable metal or ceramic parts and therefore easier to handle. Cerathane(TM) has the ability to withstand much higher loads and impact than does alumina ceramic. Cerathane(TM) also absorbs noise whereas metal and ceramic generate noise.
Cerathane(TM) will also withstand higher temperatures than rubber or standard polyurethanes making it suitable for these applications.
From mining screens and trommel panels to steel mill rollers, from automotive componentry to chute linings, from pump impellers to cyclones, Cerathane(TM) can provide a better solution.
Longlife
Multotec Longlife was specifically compounded for wear resistant secondary and tertiary screening applications within the mining industry. This material is a unique blend polyurethane, ceramic and other additives to give exceptional life in small particle sliding abrasion applications. The technical staff at Multotec taken the latest polyester polymers to produce a material with outstanding abrasion and tear resistance, excellent load bearing capacity and resiliency.
We can also tailor this material to your specific application to ensure the best performance under the most demanding conditions.
Wearblazer
Designed to monitor wear in any application, Wearblazer is a two colour polyurethane lining made to order. It enables easy scrutiny of wear and is designed to enable maintenance and engineering staff to easily monitor the wear in chutes, bins, tanks etc.
Wearblazer can be manufactured in conjunction with any of our advanced composite materials to bring a new dimension in preventative maintenance.
The light yellow base colour enables wear areas to be assessed and replacements planned. Our technical expertise may enable the engineering of better solutions through this monitoring, and ensure less down time.
The image below shows a 28mm overall thickness Wearblazer liner plate. The 28mm consists of 4mm MS backing plate complete with M12 studs, 12mm yellow and 12mm red high wear resistant polyurethane.
Fire Resistant Anti Static
Multotec can compound materials with a Fire Resistant Anti Static additive formulated to produce a polyurethane which will self extinguish combined with reduced electrical resistance. It will satisfy Electrical Resistance AS1334.9 and Fire Resistance AS1334.10.
Food Grade
Food grade polyurethanes are available for applications in the food processing industry and in grain and sugar handling facilities. These polyurethanes can be compounded in a number of different hardnesses to suit a wide variety of applications.
