RTM and Infusion

Preferred by the world’s leading composites parts manufacturers Poliya’s Infusion / RTM type resins have low viscosity, excellent fiber wet-out and flow properties which makes them ideal resins for marine applications, wind turbine blades and construction applications. Polipol 3382, with high HDT value and Polipol 3567, with minimal shrinkage are resins for RTM applications in vehicle parts, water slide productions. 

 

Polives 702 vinyl ester resin is preferred for infusion applications for boats, yacht, wind turbine blades productions and has high hydrolytic resistance and high mechanical properties. 

RTM production method allows for high quality GRP parts on both surfaces.

Resin Infusion Application

Infusion production method recommended for applications like production of marine vehicles and wind turbine blades. It is also useful for the automotive industry in production of low volume parts. Primary purpose is cutting down VOC emissions with high glass fiber ratios of up to 70% and homogeneous distribution of resin through out the part body without air entrapment. Composite parts produced with the infusion method have exceptional mechanical strength. 

 

Resin Infusion Products 

 

Both Polives 701-TA skincoat and 

 

Polives 702 Infusion type vinyl ester 

 

resins are recommended for infusion. 

 

Silicone Membrane System 

 

L–RTM and Infusion resins can 

 

be used with vacuum bags and/or 

 

reusable silicone membranes.

RTM - Resin Transfer Molding

Composite production with RTM method has the following advantages: good surface appearance on both sides, low workmanship, better dimensional stability, lower styrene emission, high productivity. Because of these properties, it is an ideal method for the production of vehicle parts with or without gelcoat. 

 

RTM production steps: 

 

① Apply mold release agent on mold surface 

 

② Apply a gelcoat film of 500-800 microns 

 

③ Lay down reinforcement material on cured (but tacky) gelcoat 

 

④ Close upper mold 

 

⑤ Apply vacuum to seal mold 

 

⑥ Apply vacuum inside the mold if needed 

 

⑦ Check peroxide ratio and equipment pressure 

 

⑧ Inject resin into the mold 

 

⑨ Stop injecting when resin capacity is reached 

 

⑩ Demold the composite part after resin finishes curing 

 

RTM and Light RTM production provides a faster composite part production rate with shorter cycle time compared to hand lay-up or spray-up production methods.

 

Incorporation of heating-cooling systems to molds will also speed up production rates.
