Have you ever wondered why some silicone spatulas are exceptionally soft while some silicone molds are rigid and well-shaped? Behind this lies the role of material "hardness". Our specially developed liquid silicone rubber for kitchenware, the IOTA LSR 3750 Series, offers a total of six hardness options ranging from 20 Shore A to 70 Shore A, easily meeting the requirements of different kitchenware products.
What exactly is "hardness"? Here’s a simple way to understand it:
Hardness refers to the degree of softness or hardness of a material. The lower the value, the softer the material; the higher the value, the harder it is.
-
20-30 Shore A: Extremely soft, suitable for making sealing rings, soft spatula heads, and baby bottle nipples.
-
40-50 Shore A: Moderately tough, commonly used in baking molds, placemats, and oil brushes.
-
60-70 Shore A: Relatively hard, applicable to items that require shaping, such as lunch box latches and tool handles.
In addition to the selectable hardness, the 3750 Series also boasts these advantages:
-
1:1 mixing ratio: Simple to operate during production, with low risk of errors.
-
Excellent fluidity: Easy for injection molding, capable of perfectly filling even complex structures.
-
Rapid curing: Improves production efficiency and reduces energy consumption.
Performance explained without "jargon":
-
Tensile strength up to 10 MPa: This means it can withstand strong pulling forces without easily breaking.
-
Elongation at break up to 650%: It can be stretched several times its original length and still rebound, with minimal deformation.
-
Tear strength up to 40 kN/m: Effectively prevents the expansion of surface cracks.
Wide range of applications:
Whether it’s flexible silicone spatulas, shape-retaining cake molds, or kitchen gadgets with complex structures, the 3750 Series can handle them all with ease, achieving "one material, multiple possibilities".
Conclusion:
In kitchenware manufacturing, materials are the soul of products. With its flexible hardness options and stable performance, the 3750 Series provides kitchenware designers and manufacturers with more possibilities to turn their creative ideas into reality.
