RTV-2 Liquid Silicone Rubber for Making Silicone Shoes Insole/Foot Pad/Toe Separator
Soft Casting Footware Shoe Insole Liquid RTV2 Silicone Rubber is great to make silicone insoles and related foot health care products, such as heel lifts, Insoles, foot orthotics , arch supports, heel cushions and pads, etc. It is a medical grade silicone that resists to bacterial growth and does not dry out. It is also hypo-allergenic, non-toxic and odorless.
| Item | Mixing Ratio | Color | Hardness (Shore A) | Viscosity (mPa·s) | Working Time (25ºC) | Curing Time (25ºC) | Tear-Strength (kN/m) | Tensile-Strength (Mpa) | Elogation (%) | Shrinkage (%) |
| OTT-X708 | 1:1 | clear | 8 | 2200 | 10-20mins | 1-2h | 10.1 | 2.2 | 500 | ≤0.1 |
| OTT-X710 | 1:1 | clear | 10±2 | 5000±1000 | 5-30mins | 1-4h | ≥6 | ≥2.0 | ≥600 | ≤0.1 |
(Note: Other hardness is adjustable,customers can use silicone oil to lower the hardness and viscosity of J825 according to their special requirements.)
Features:
1.Almost nil shrinkage
2.Good fluidity, operability and excellent operation
3.Good resistance to weather, temperature, aging, acid
4.Excellent tear strenght, comfortable duplcation times
5.High chemical resistance to aggressive components of some types of resins
6.Food grade silicone(environmental, odorless and nontoxic
7.High resistance to high temperature and aging(resist -60 to 200ºC)
1. Make sure the surface of the original is clean and free of loose material.
2. Weight 100G Part A base and 100G parts B in a clean container.
3. Stir Part A base silicone before use thoroughly , as filler separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until completely dispersed in the base.
5. Pour the mixed base silicone and platinum curing agent as soon as possible onto the original
6. De-mold after 24 hours ,it is will improve the replicate times of silicone mold.
Note:It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 min under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.

1. What's silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. What is your MOQ?
Our MOQ is 200kg. But usually we accept less quantity such as 100kg on the condition that sample charge is 100% paid.
4. How about the quality control in your factory?
--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment.
5. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.
6. How to get good silicone mould to use longer time?
--The best way is:
#A, Please choose the right liquid silicone according to your products.
#B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
#C, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.
7. Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
