MILAN—Laser marking liquid silicone rubber became tested on the Silicone Elastomers Summit, backed through Smithers Rapra, in Milan.

The demonstration concerned REA Jet FL fiber laser marking equipment from Mühltal, Germany-primarily based REA Elektronik GmbH.

The Merck KgaA laser advertising pigments have been dispersed in Alpa-LSR 550201 and 550202 laser marking grades from Tuebingen, Germany-based mostly CHT Germany GmbH.

The project, which made baggage tags, become produced via Freiberg, Germany-based mostly LSR and thermoplastics molder Antech Polymertechnik.

CHT's laser marking grades have compression set 12, Shore hardness 50A and viscosity 300 mPas at 10/s. however values vary for elongation to wreck at respectively 380 and 300 and tensile energy at respectively N/mm2 and N/mm2.

depending on laser beam depth, markings range from gentle grey to black, on opaque colored or transparent LSR constituents, together with deeply engraved marking where required.

actual foaming

also at the Silicone Elastomers Summit, Svenja Marl, a researcher at the UNIpace polymer application middle at Kassel tuition in Germany, spoke about actual foaming LSR. Colleagues had proven water as a foaming agent at the 2017 summit.

Marl offered microscope photographs of foam structures from 2-four percent water displaying nonhomogenous mobile distribution. mould temperature has gigantic have an effect on on constitution: at 140° C, no foam structure close to the epidermis and principal tough pores; absolutely foamed constitution at one hundred eighty° C, but nevertheless significant tough pores.

She then moved onto the next development stage, mixing LSR with Expancel 031 DU forty expandable thermoplastic microspheres from Stockviksverken, Sweden-based Akzo Nobel Pulp and performance chemical compounds AB.

Researchers, in the meantime, also used Unicell MS one hundred forty DS expandable microspheres from Tramaco, Taiwan. As with Expancel microspheres, these spheres consist of a 2µm-thick 15-20 µm diameter shell crammed with hydrocarbon. Marl revealed Unicell microspheres encompass an acrylonitrile/methacrylate copolymer, expanding at 120-a hundred twenty five° C to a 50 µm sphere with a µm thick shell.

UNIpace used weight % Unicell microspheres in LSR. Foaming became respectable at 1 and a couple of wt the latter giving better Shore hardness as a result of filler network formation. The microspheres had in the beginning reduced hardness with filler content material as much as wt percent.

whereas 50 percent weight discount changed into received with Expancel foaming earplug information in Dow Silastic LTC 9400-50, weight discount became decrease at 30 percent when molding foam discs and spheres in KEG-2003H-40, a Shin-Etsu Silicone LSR grade from. In usual, Marl spoke about 35 weight discount being feasible with Unicell MS a hundred and forty DS.

substances

In a "low is the new excessive" presentation, Patrick Beyer of Dow Silicones showed advantages of latest low-viscosity, low-compression set, low-temperature treatment and low-volatility LSR grades.

Low viscosity Silastic RBL-9200-50 retains low viscosity prior to injection into mildew cavities, enabling lower injection drive and higher injection speeds, with benefits of a sooner cycle time, a much wider procedure window and more suitable consistency.

Dow reduced compression set in LSR by way of suppressing thermo-oxidative decomposition and reactive group presence in cured LSR that react with hydrosilation under compression, time and at elevated temperature, to kind new move-links and everlasting deformation. The result is enhanced sealing performance beneath harsh situations and elimination of submit-remedy medicine.

Beyer recommended these advantages become crucial as automotive below-the-hood temperatures proceed to upward push with engine downsizing, additionally to meet new technological necessities coming up with shifts to electric pressure vehicles and self sufficient riding.

Silastic NPC 9300-xx sequence low risky nonpost-remedy grades customarily have % certified volatile content, now not influenced between a hundred and twenty° C press cure temperatures appropriate as much as in-mould curing of injection moldings at up to 200° C.

Dow Silastic LTC low-temperature cure grades address significantly longer cure times at decreased temperatures, which are required when overmolding LSR to lower-temperature thermoplastics and delicate add-ons.

while remedy time hardly differs vs. ordinary LSR at one hundred fifty° C, Beyer showed it being 60 faster at a hundred° C, yet with an extended seventy two hours pot lifestyles. He confirmed a success molding of a LTC grade to Dowlex 2035, a C Vicat softening temperature polyethylene. As LTC grades have a low diploma of temperature gradient sensitivity, they can be used at higher temperatures to acquire fast deep-part remedy in thicker moldings.

Reviewing new self-bonding LSR grades, Clemens Trumm, global application development core supervisor at Momentive efficiency materials GmbH in Leverkusen, Germany, said peel strength against different substrates should be at a lower stage and rising extra slowly all through half demolding. but this requirement works towards the want for quite excessive bond strength mandatory to demold extremely complex components.

Momentive proposes UV-curing LSR grades for bonding to polyolefins. They do not require submit-treatment medicine, but at the least a part of mold cavities need a clear PMMA window.

Silopren LSR 2730/2740/2750 self-bonding grades were attainable due to the fact at least 2014.

Trumm implied the competencies to dispose of plasma medicine, used to raise surface tensile power from 45 mN/m to 85 mN/m on a polycarbonate lens overmolded by using polybutylene terephthalate and then LSR. The system limits between the LSR and polycarbonate in a multicomponent rain-and-gentle sensor molded on account that 2010 by means of Esslingen, Germany-primarily based molder and mildew maker Weber-Formenbau GmbH & Co. KG.

Momentive illustrated polycarbonate bonding by using molding a cell holder at NPE2018 in Orlando, Fla.

he LSR 27x9/47x9 grades supply low temperature cure, do not have submit-cure warmth treatment and have "targeted adhesion," so that while bonding smartly to notebook and copolyester, the materials do not adhere right through molding to metal mould and cold runner metallic surfaces.

Trumm pointed out work now focuses on gentle/challenging combinations with new BPA-free resins, adhesion to UL94 V-0 flame retardancy resins and low temperature cure with longer pot existence.

large facts

Stefan Roenisch, global manufacturing engineering LSR at Aptiv services Deutschland GmbH in Wuppertal, Germany, described how trade ideas improve silicone rubber molding.

As a huge molding plant with one hundred sixty LSR machines operating with 16 colors, high-quality emphasis is placed in Wuppertal on the use of facts to optimize molding methods and displaying it on significant display screens throughout the plant.

These inform administration, production, renovation and toolshop staff about molding machines' live status, deliberate vs. completed cycle times, downtime explanations, planned preservation schedules and gear servicing, and fabric changeovers.

a high quality assurance dimension trolley connects to molding machines by the use of each and every laptop's interface, calling up records on the genuine circumstance are living, overviewing statistics on the ultimate five packing containers stuffed, recording last check time stamping and scanning excellent verify outcomes.

Roenisch illustrated how information generated for the reason that monitoring become first brought in January 2016 superior manage of mildew fouling, which depends upon many components, equivalent to climate, storage circumstances, material properties, laptop settings, colour masterbatch and mould cleansing strategies.

Discussions begun with LSR cloth suppliers in June 2016 based additional factors that get rid of mould fouling "when used in the correct combination" — for example, platinum catalyst, cross-link agent, water and silane contents, filler remedy, water/silane, stripping time.

Roenisch concluded, "If we share our massive records with business enterprise records, we get real huge facts, as has been used to conquer mold fouling."
