 Injection moulding silicone rubber HY-940  Standard Datasheet for medical grade:

Application

1.Separate or wipe clean the toolsof part A,B before use , orit may cause the product can’t working normally because of the A&B mixedand local agglomeration

2.The effective operating time is 4hours after the uniform mix between part A&B

3.During the rubber operation, avoidcontact the compounds which contains the N, S, P, Sn, etc, or it will causeincomplete curing or not curing.

4.The best mix ratio is A/B=1:1, toolarge or too small will influence the final product performance

How to use 

1.Mixed A with Baccording to mixing ratio of 1:1 through the static mixer,then injectingthe mixed rubber into the mold through the injection machine, the rubber mustbe full filled(hand-mixing isfeasible, poured into the mold for molding)

2.Recommendedmolding conditions: 140°C/40-60s (thickness 2mm).

3.Testand determine the specific conditions of molding according to the thickness orsize of product

4.Ifthe bonding between the special material and silicone rubber is needed(e.g. PET,PC, iron andsteel materials, etc.you can check the accessory products of the silicone adhesive about our company )

Storage

Safe

1.Note the labor wearable during the application, avoid high-temperatureburns during the construction process, and prohibit consumption.

2.Use the product carefully, note the safety issues before and during use, moreover, follow the relevant provisions of national or local government safetyregulations. (Refer to the appropriate safety guidelines for details in MSDS)
