SecondLife MineralsWhat is the shot content?
Not yet measured on the finished stream. The wash and de-shotting loop is designed to reduce it, but until it is measured per lot we will not publish a number. Ask for the current lot data before you plan around a figure.
SLM-FB
SecondLife Mineral Fiber
Washed, dried, de-shotted loose mineral fiber, spun from the same melt as stone wool insulation.

What this kind of material is used for
Mineral fiber of this general type is used in the processes below. Every one of them qualifies a fiber supplier against its own specification, and this fiber has not been through any such qualification.
- Reinforcement and friction-modifying fiber in friction material formulations
- Drainage-inhibiting fiber in stone matrix asphalt
- Filler and reinforcement fiber in gaskets and sealants
- General high-temperature mineral fiber applications
Who buys it
- Friction material compounders
- Asphalt producers running stone matrix asphalt mixes
- Gasket and sealant manufacturers
- Industrial fiber distributors and tollers
Not established yet
This material carries handling considerations that the coarse materials do not, and they are stated here rather than left to the safety data sheet alone.
- No loss-on-ignition measurement. Whether this fiber carries residual binder is unmeasured, and friction formulations typically specify a low loss on ignition. This single test decides whether the friction channel is open at all, and it has not been run.
- No fiber length or diameter distribution, and no measured shot content on the finished stream.
- No qualification against any friction material or asphalt specification.
- Handling: this is a loose respirable-scale fiber and requires dust control and personal protective equipment. A safety data sheet specific to this material has not been written yet; the existing 10X sheets cover abrasive granules, not loose fiber.
Questions buyers ask
About Mineral Fiber
Is there binder in it?
Unknown, and we would rather say so. A loss-on-ignition test answers it and is scheduled. If your formulation requires a low loss on ignition, wait for that result before spending time on a sample.
Is it safe to handle?
It is a loose mineral fiber and should be handled with dust control and appropriate protective equipment. The parent material was classified by IARC in 2002 as Group 3, not classifiable as to carcinogenicity in humans, and is not listed by the National Toxicology Program. A safety data sheet specific to this fiber is being written and we will not ship a sample without one.
