The new translucent medical grade compound prepared by Foster (Putnam, CT) has a reduced coefficient of friction (CoF) when added to low hardness thermoplastic polyurethane (TPU) and Pebax polyamide elastomer materials.
Similar to the existing ProPell product line, the new ProPell T material reduces the coefficient of friction while maintaining critical mechanical properties and improving the manufacturing and handling of medical catheters. In addition, Foster said: ProPell T products offer a proprietary surface additive that provides translucency that is different from any product currently on the market.
Translucency is essential for medical applications that require close visual surveillance. "Not only can medical personnel see the material being transported through translucent medical supplies, but they can also easily detect any defects in the equipment," explains Larry Johnson, vice president of business development.
ProPell T technology reduces the stickiness and friction of medical device components, especially soft, pliable polymers, such as low-hardness TPUs commonly used in central venous catheters and Pebax polyamide polymers for interventional vascular catheters.
"The use of ProPell T material in catheters has many benefits for medical practitioners, as it provides easier deployment and control of the catheter, allowing the catheter to move faster and more smoothly through the vascular system," Johnson added. In addition, ProPell T technology reduces the stickiness of injection molding equipment.
