Polimotor Partners with Industry Suppliers to Develop Next Generation Plastic Engine

Polimotor LLC and its founder, Matti Holtzberg, have partnered with industry suppliers to help develop Polimotor 2, the next generation of polymer engines.


Permatex has partnered with Polimotor LLC and its founder, Matti Holtzberg to help develop Polimotor 2, the next generation of polymer engines. The Polimotor 2 engine was designed with fiber reinforced polymer engine parts that are used in place of some of the traditional metal components, in order to reduce weight. Weight reduction is a critical factor in both racecars and everyday vehicles in order to maximize fuel economy and horsepower.

The Polimotor team uses Permatex sealants and gasket makers exclusively on the Polimotor 2, which is built without the use of any traditional preformed gaskets other than the head gasket. Permatex RTV gasket makers are used to effectively seal and to deliver both leak proof and fail proof performance.


In response to the growing demand for lighter and more fuel-efficient cars from global automakers, Holtzberg has taken his design to the next level and created Polimotor 2, using his latest fiber reinforced polymer materials for manufacturing engine blocks. The Polimotor 2’s polymer engine block, oil pan, cam box, and cam cover are molded using a fiber-reinforced thermoset molding compound and a molding process developed by Holtzberg. The Polimotor 2 block weighs 13 lbs. less than Ford’s latest Ecoboost 2.0 aluminum block.

In addition to Permatex, other key automotive manufacturers have also joined the Polimotor team including: Solvay, PolyOne, Toho Tenax, AGY, Mobil 1, and Mahle.
