For example, in long fiber filled compounds, compression molding gives the greates strength. Phenolic resins are used as bonding and impregnating materials. Bonding resins are available as pure compounds, but are more formlated with elsastomers and fillers to provide special properties. Good compressive strength. Resilient materials obtained by modifying with rubber of nylon.
Limitations are that forms are hard and brittle.
Impact strength not high except with cord, fabric, glass and butadiene filled grades. Hence high breakage rates during transportation have been reported. Good dimensional stability over wide temperature range. Self extinguishing grades available. This can be extended depending upon fillers used.
