HYBRIDS : LIQUID SILICONE RUBBER LSR SELF BONDING ON TP - THERMOPLASTIC (2on2) also named "self bonding lsr silicone"
On 27-03-2013
"Composites" systems took a new place which “conventional systems” did not occupy for :
- integrating many functions into the same component (ex : case/seal)
- solving assembly problems (ex : diaphragm on micro part)
- function improvements (ex : no seal sliding on assembling)
In "1on2" communication ( INFORMATION LETTER N°57 CHEVALIER - CLERET - ELTEC ) we informed you about “traditional rubber adherisation” on support. In that present communication, we are going to explain you a different and innovative process allowing silicone rubbers polymers adherisation ( to stick ! ) on various supports.
Self bonding silicone LSR chemical sticking on support : Some LSR specific and quite new silicone grades allow to get support adherisation without adherisation agent treatment.
It is necessary to check compatibility and adherisation quality between support and self bonding LSR (support can be TP : PA - PBT - PPS; glass; metal...). Many characterization tests have already been realized: do not hesitate to reequest for us !
LSR reticulation is made around 180 °: cycle time depends from thickness, and is from 10 to seconds (usually); supports can not allow (due to heigt temperature deformation, flow…) these constraints are not so recommended.
SILICONE main characteristics reminder :
- working temperature good behaviour: - 50 °C until + 180 °
- good chemical resistances and good ageing (UV, colour…)
- much better mechanical performances than TPE : low hardness and modules, good various resistances
(compression set…)
- available food and medical-pharmaceutical grades : certifications Bfr, USP cl IV and FDA...
- “easy” process and "clean" / coloration is also easy even if limitated
- hardness from 10 to 70 shore A according to grades and very low modules associated with the lowest hardness
- self lubrification grades availability: "non compatible silicone oil" is present inside material and is "bleeding" in time=> this avoids seal lubrication and is easy for assembly
