Product Description

IOTA FLSR8400 addition-type liquid fluorosilicone rubber

Description:
The IOTA FLSR8400 series two-component addition-type liquid fluorosilicone rubber is a liquid polymer material made from polyfluorosiloxane containing ethylene as the base rubber, low fluorosiloxane containing silicon hydrogen as the crosslinking agent, and reinforced with fillers, using a platinum vulcanization system. It has excellent high and low temperature resistance, oil resistance, and electrical insulation, which can maintain stability in harsh environments for a long time. It is fast and convenient to form, has a short processing cycle, and a wide range of operating temperatures. It is very suitable for producing oil resistant parts in the fields of automobiles, ships, aerospace, power and electrical engineering. Additionally, it can be further expanded to consumer electronics, wearables, and healthcare, with broad application prospects.

Usage:
IOTA FLSR8400 series liquid fluorosilicone rubber is a two-component material, components A and B, packaged separately.

When in use, mix components A and B in a 1:1 weight ratio by mass in a three-roll mill or planetary mixer, then degas the mixture, molding and coating, curing can be achieved. The vulcanization process by an injection molding machine can be directly controlled by the platform.

Curing Conditions:
The curing time of the IOTA FLSR8400 series liquid fluorosilicone rubber depends on the curing temperature, thickness, and size of the cured product. When heated to 120°C, rapid curing can occur within a few seconds, with the rate optimized according to the size of the component. Recommended curing conditions are 1st curing at 120°C for 10 minutes and 2nd curing at 200°C for 4 hours. Please adjust the curing time reasonably according to actual production process.
Packaging: 
Packed in 20kg/plastic drums

Shelf Life: 
Store in a cool, dry environment, shelf life is 12 monthes in unopened original packing.

Precautions:
Avoid contact with compounds containing nitrogen, sulfur, phosphorus, and heavy metals to prevent incomplete vulcanization or non-vulcanization of the product.

 

1.Q: What is liquid silicone rubber?

A: Liquid silicone rubber is a form of silicone rubber commonly used in the manufacture of baby products such as baby pacifiers. It is composed of silane monomer and cross-linking agent and has properties such as softness, high temperature resistance and chemical corrosion resistance.

2.Q: What are the advantages of liquid silicone rubber nipples?

A: Liquid silicone rubber nipples have the advantages of high temperature resistance, easy cleaning, softness and comfort. It does not contain BPA, is not easily deformed, has high durability, and is less irritating to the baby's mouth.

3.Q: Are liquid silicone pacifiers safe?

A: Yes, liquid silicone nipples are generally considered safe. They are rigorously tested and certified to ensure they meet safety standards and do not contain harmful substances such as BPA, PVC, etc.

4.Q: What issues should we pay attention to when using liquid silicone rubber nipples?

A: It should be carefully inspected before use to ensure there are no cracks or wear. At the same time, avoid exposure to sunlight for long periods of time to avoid affecting the material quality.
