Known worldwide as standard ballistic clay, Roma Plastilina No1 is a homogenous non hardening, oil based modelling clay and is the designated backing material for the testing of ballistic vests to both NIJ & HOSDB standards. The ballistic clay comes in a case of 20 bricks. Each brick measuring 140mm x 63.5mm x 76mm and weighing 2-lbs or 907 grams. Color is gray-green.
The NIJ, HOSDB, SK, ISO and other testing standards from around the world involve firing different types of bullets ranging from 9 mm to .44 Magnums and up to caliber 12/70 shotgun slugs, at body armor placed in front of a tray of ballistic clay, a material that emulates the human body.
Typically these standard tests require vest designs to stop multiple shots at a certain velocity, and the clay must have less than a specified residual cavity depth commonly referred to as “back face signature deformation”. For example, the NIJ specification requires six shots with less than 44 millimeters of "back face signature deformation".
- Military specified along with specifications of other testing around the world
This is the world stand testing material for all ballistic testing
- Stable at room temperature.
Unlike gelatin, water-soaked materials, or water-based clay, Roman Plastilina No 1 Ballistic Clay remains the consistency of animal muscle tissue without refrigeration.
- Ready to use without mixing.
Roman Plastilina No 1 Ballistic Clay does not require mixing, so it maintains the same consistent density from test to test.
- No refrigeration required.
Roman Plastilina No 1 Ballistic Clay can be used without refrigeration, unlike water-based gels which spoil or need to be refrigerated to consistent temperature to maintain their density from shot to shot. The testing can be done in the field.
- Re-usable, re-castable.
Roman Plastilina No 1 Balistic Clay can easily be melted and re-cast. It quickly sets up for another shot.
- Closest simulation of actual tissue.
Roman Plastilina No 1 Ballistic Clay is an excellent match to the density and elasticity of live animal muscle tissue, providing a superior simulation for bullet testing and forensics.
Roman Plastilina No 1 Ballistic Clay is non-toxic, has a very low incidence of reaction, and has no known health hazards associated with handling or use. It has a faint odor similar to wax. If bullet fragments contaminate the material, it can be cleaned by melting and filtering.
