Reaction Injection Molding Vs Plastic Injection Molding

Reaction injection molding is also different in that, by nature, two base polymers are combined (as opposed to plastic injection molding, where materials can be combined, but it isnt required). The two materials must be combined because they then cause a reaction that causes the material to fill the mold cavity via expansion.
