If you’re wondering about the storage duration of your rubber mold in a “mold library,” commonly referred to as Library Life, this article will provide you with the necessary insights. Understanding the longevity of your rubber mold when it’s simply sitting on a shelf, waiting to be utilized, is crucial for efficient mold management. Different mold rubbers have varying durability, so let’s explore the approximate library life you can expect from various types of mold rubbers.
- Factors Influencing Library Life
Before diving into specific mold rubbers, it’s important to consider the factors that can affect the library life of your rubber molds. While these factors may not be identical for every mold, they can provide general guidelines for proper mold storage:
- Storage Conditions: Proper environmental conditions play a vital role in preserving the integrity of rubber molds. Ensure the storage area is clean, dry, and free from excessive heat or sunlight, which can accelerate degradation.
- Mold Design: The complexity and intricacy of your mold design can influence its overall lifespan. Molds with delicate features or thin sections may have a shorter library life compared to sturdier counterparts.
- Mold Material: Different mold rubbers possess unique properties that impact their durability and longevity. Understanding these characteristics is essential for selecting the right mold material for your specific needs.
Now, let’s delve into the library life you can expect from various mold rubbers:
Urethane (polyether based) : 25+ Years
Urethane (polyester based) : 1-7 Years (Moisture Exposure Dependent)
Silicone (tin based,economy) e.g. RTV-6 series: 1 Year
Silicone (tin based, strength) e.g. T-Flow, T-Pro : 5-7 Years
Silicone (platinum based) e.g. P-series, VB, HC: 30+ Years
Latex: 10+ Years (With Proper Care)
Vinyl: 5+ Years (With Proper Care)
