Some of the properties of 450G and 150G are compared in the table below to illustrate these differences. This is a consequence of the shorter polymer chains, which are less entangled, crystallise more readily and to a greater overall extent. However, the lower molecular weight also changes the bulk properties of the polymer: lower molecular weight PAEKs have higher stiffness and strength combined with reduced toughness, ductility and impact resistance. As a result, 150G may be more suitable for applications where lower viscosity in the melt during processing is desirable, for example, when injection moulding thin-walled parts or long, thin sections with intricate geometries impregnating carbon or glass fibres for composite prepregs or adding high levels of solid fibrous or particulate fillers and reinforcements to make compounds. VICTREX PEEK 150G is a higher flow, lower molecular weight, lower MV grade of PEEK compared to 450G. 30 glass-reinforced PEEK comes in either natural/tan or black colors. Despite being stronger, glass-reinforced PEEK will wear more when mated to other parts. Other VICTREX PEEK grades are available with higher and lower melt viscosities and higher or lower molecular weights respectively. Polyether ether ketone (PEEK) plastic is a highly coveted engineering material, thanks to its superb blend of strength, resistances, and workability.

VICTREX PEEK 450G is defined as a standard melt viscosity (MV) PEEK grade, with a medium molecular weight. Impeccable On-time Delivery, Parts in as Little as two weeks. Properties may also differ for along flow and solve critical challenges that go beyond current material limitations, typically replacing metal. Property values are highly dependent on part geometry, mould configuration and processing conditions. VICTREX PEEK based parts in automotive applications. Data are generated in accordance with prevailing national, international and internal standards, and should be used for material comparison.Mould shrinkage is expressed as a percent change in dimension of a specimen in relation to mould dimensions.When it exits the gate and enters the mould. “Along flow” direction is taken as the direction the molten material is travelling Mould shrinkage differs for along flow and across flow directions.Actual mould shrinkage values are highly dependent on part geometry, mouldĬonfiguration, and processing conditions. Data for mould shrinkage should be used for material comparison.
