HY-924 Liquid Silicone for Injection Molding
 
HY-924 Liquid Silicone for Injection Molding is a two-component liquid silicone rubber for injection molding processes. HY-924 shows a higher productivity, high transparence,less yellowing and low volatile contents. HY-924 would be possible to increase productivity by reduce injection time and total cycle time. Also, it is easier to inject into the cavity of the mold which is more complicated designed. In addition, higher transparency and less volatile content make it most suitable for consumer products.
 
Application:
Because of the outstanding properties, HY-924 is particularly suitable for the following elastomeric articles: baby nipples, medical tubs, keypads, bellows, vibration dampers, air vent flaps, switch covers, pressure cookers parts, cable connectors s.o.
 
Specification:
Vulcanisates consisting of  HY-924 are distinguished by the following properties:
·High productivity, high transparence
·High flowability, low viscosity and short injection time.
·Low volatiles content; Fast cure
·Excellent mold release, Excellent Thermal stability
·Excellent compression set; Excellent resilience
·High stability to ozone and ultraviolet light
·Outstanding resistance to ageing
·Not readily combustible, does not melt or drip
·Easy-pigmentable with LSR Colour Pastes fulfill the requirement of KTW

Processing Recommendations
Ready-to-use mixtures (of the components A and B) are fed directly to the injection molding machine from the original containers by means of a metering and mixing unit. The mixture, consisting of the two components in the ratio 1:1, is injected into the heated mould. Because of low viscosity, the injection daospeed and injection pressure need to be carefully adjusted so that the injection time can be decreased. At mould temperatures of 170 - 230°C, the addition -crosslinking silicone rubber vulcanises free of dissociation products within a few seconds. Excellent flowability and easy demoulding permit fully automated production of large numbers of articles in shorter total cycle times.
SHELF LIFE:
