Large-scale production

Impro is uniquely positioned to reliably meet high-volume demands quickly and efficiently. Our factory is home to the world’s largest glove dipping facility, with dedicated production lines for industrial work gloves and disposable nitrile gloves.

We also have direct access to manufacturing materials with our own in-house Rubber Formulation Center and a stand-alone production facility for our synthetic materials. This positions Impro with robust capabilities in both sourcing and manufacturing, allowing us to scale production on demand.

Unrivaled quality and cost-efficiency

Best practices guide every production process at Impro. We maintain third-party certification in our systems for quality, environment, and social impact, following both domestic and international standards for worker protection, equipment maintenance, and product quality.

All factory operations are monitored by a central Distributed Control System (DCS), providing oversight at every link in the production chain. This end-to-end insight is what allows us to optimize for efficiency, driving down manufacturing costs for us and our clients.

Performance testing

Our facilities are equipped with world-class analytical instruments and simulation technology, capable of testing all areas of product performance.

Instron universal test

EN 388-6.4 Tear resistance

Tear resistance is measured using an advanced Instron Universal Testing system, which calculates the force required to tear a rectangular material sample along its length.

Coupe cut test

EN 388-6.2, GB/T 24541 Blade cut resistance

The test glove is exposed to a counter-rotating circular blade, making alternating cutting motions at prescribed loads to measure blade cut resistance.

TDM-100 test

ASTM F2992, ISO 13997 Cut resistance

Machine measurement of the downward force (in Newtons) required for a blade to cut through the Test glove from a fixed distance. The resulting value is then used to grade the cutting resistance of finished gloves.

Martindale wear & abrasion test

EN 388-6.1 GB/T 24541 Abrasion resistance

Test samples undergo a planar cyclic frictional motion under known pressure in a Lisharus pattern. Wear is measured by loss of mass, or number of cycles before coating exposes base fabric beneath.

Taber abrasion test

ASTM D3389 Abrasion resistance

Using a double-turntable type grinding machine, the test sample is rotated at a fixed speed under the rotary grinding action of two Taber abrasive wheels. Effects of this rub-wear action is measured at specific pressures, calculating abrasion resistance.

STM608 Anti-impact test

ANSI ISEA 138, EN 388 (EN 13594) Impact resistance

A weighted drop hammer is dropped onto test gloves from set distances. Force value and displacement sensors measure the peak impact forces withstood to grade anti-impact quality.

UV Visible Spectrophotometry (UV-Vis)

Testing for Aqueous Extractable Protein, Methanol Method Development

UV-Vis analysis, using Lambert-Beer law, to measure absorbance of substances at different wavelengths.

Gas Chromatography Mass Spectrometry (GC-MS)

Testing for DMFa, PAHs, Phthaltes

Combined molecular mass spectrometry technology for direct qualitative and quantitative analysis of complex organic matter.

Fourier transform infrared spectrometry (FT-IR)

Testing for Silicon presence and qualitative analysis of compounds

FT-IR chemical bond wavenumber analysis to identify type and structure of all unknown compounds present.

Contaminant migration

Testing for contaminant migration in foodstuffs

Determination of the total amount of all non-volatile substances migrated through contact with foodstuffs.

pH levels

Testing for acidity and alkalinity

pH level measurement of hand protection to determine suitability for intended material handling.

Organic permeation

BS EN 16523-1:2015+A1 Determination of material resistance to permeation by chemicals

Glove resistance to organic reagent permeation detected through Hydrogen flame ionization gas chromatography.

Inorganic acid/base permeation

BS EN 16523-1:2015+A1 Determination of material resistance to permeation by chemicals

Glove permeability tested through Hydrogen ion electrode method, detecting for concentration of acids or bases in aqueous solution.

Liquid tightness

BS EN ISO 374-2 Determination of resistance to penetration

Test glove is filled with water. Leaks are detected by the appearance of water droplets on the surface of the glove.

Airtightness

BS EN ISO 374-2 Determination of resistance to penetration

Test glove is immersed in water and its interior pressurised with air. Leaks are detected by the presence of air bubbles escaping the surface of the glove.

Softness

Test material is pressed into a gap of set depth by a plate probe. Softness is calculated through the measured bending force of the test material.

Stiffness

Resistance to bending, or stiffness, measured by the maximum force required to push a flat, folded swatch of fabric through a small opening.

Breathability

Measuring airflow rate across a fixed, cross-sectional area, calculating material breathability performance via pressure delta.

Heat contact resistance

Test glove is worn by a tester to grasp an element set to a fixed temperature. Heat resistance is determined by the time elapsed before the tester feels unable to withstand the heat of the element.

Thermal insulation

Test glove is placed in a calorimeter and gradually brought into contact with a heating cylinder set to a fixed, high temperature. Thermal thresholds are determined by monitoring temperature changes in the calorimeter.

Full hand grip performance

Full hand and thumb clamping tests, measuring force values and tester comfort when pulling loads to determine overall anti-slip performance.

Sliding friction

Measurement of the tension required to slide the test glove uniformly on a flat plate under the action of a heavy object, determining its sliding friction coefficient.

Oil-based friction

Tensile and grip strength are measured under oily conditions, determining the friction coefficient of the test glove.

Static friction

Material static friction force levels are calculated by measuring the angle and displacement of the test glove when it begins to slide.

Grip performance

Testers attempt to grasp a variety of smooth conical blocks to measure versatile grip performance.

Thermal/oxygen aging chamber

Test gloves undergo heat resistance and gas exchange aging tests to assess performance when stored and used in high temperature environments. Test gloves are also subject to simulated, open air aging under variable atmospheric pressures and temperatures, with performance then measured against an unaged glove.

Dynamic Light Scattering (DLS)

Particle size and potential of latex

Accurate, non-invasive nano-particle analysis using DLS, measuring size distribution of molecules and particles within test materials, as well as surface charge variation and colloidal stability (Zeta potential).

Liquid chromatography

Molecular weight testing

Liquid chromatography is used to measure the molecular weight of polymeric materials, such as synthetic latex, to analyse and classify test materials.

High quality hand protection, made to fit.
