Speciality Chemicals
Expertise Across Industrial & Performance Chemicals
Exwold has spent decades refining contract solids processing for high-performance speciality markets, building long-term partnerships based on technical reliability. We understand that sectors such as Polymer & Plastic Additives, Flame Retardants, and Coatings require materials that not only perform chemically but are also easy to handle during downstream manufacturing. Our granulation and compaction technologies allow us to transform fine, difficult-to-handle powders into free-flowing, low-dust formats that improve dispersion and safety. This expertise extends to the rigorous demands of the Oilfield and Catalyst sectors, where we produce robust granules designed to withstand harsh operational environments while maintaining their reactive efficiency and mechanical integrity.
Solutions for Consumer, Safety, and Environmental Applications
Beyond industrial additives, we provide bespoke processing for sectors where end-user safety and precise dosing are critical. In the Home & Garden market, we help clients create consumer-ready formulations that combine shelf-appeal with safe handling. This attention to safety and efficacy is equally vital in our work with Biocides & Water Treatment, where we formulate active agents into stable solid forms that ensure accurate release in water systems. Furthermore, our capacity to handle large-scale seasonal demands makes us a key partner for Solid De-icers, ensuring that critical infrastructure and aviation sectors have access to high-performance, rapid-action products exactly when they are needed.

Case Studies
Surface Coating Blending
A multinational company required a cost-effective 2mm granule of a waxy product used as surface coating additive .
The product had not been previously extruded. The material was supplied as a waxy solid block with a melting point below 100 ºC.
The material also required careful handling as it was corrosive and a significant aim was to reduce contact hazards.
Surface Coating Additive Milling
Exwold was approached by a leading chemical company to process a range of automotive surface coating additives.
The surface coating additive is produced as a molten solid in drums. Once cooled it forms a waxy, solid mass. The material has a low melting point <50ºC. The client required this in physical form to charge into coating with a specific particle size distribution to ensure dispersion.
Coating Processing
A powder coating manufacturer contacted us to establish whether a process could be established to recycle fines (the fine powder generated and removed during powder coating manufacture).
The company was sending around 10-25mt of fines to landfill each year and wanted to reduce the environmental and financial impact. The fines ranged in PSD but were typically 150 microns.

Reports
ESG Report 2025
Our ESG Report embodies our commitment to sustainability, ethical business practices, and transparency. Through this report, we detail how we measure and manage our environmental impact, uphold human rights and employee well-being, and enforce high standards of corporate governance. By doing so, we build trust with stakeholders and demonstrate accountability, showing that profitability and responsibility can go hand in hand.
Particle Size Distribution
Particle Size Distribution (PSD) is a key factor that determines how powders and granular materials behave during processing and final use. Even with identical chemistry, variations can affect flow, stability, reactivity, and product appearance.
This guide outlines what PSD is, why it matters, and how effective measurement and control lead to greater efficiencies and quality.
Frequently Asked
Questions
Can you perform batch processing?
Exwold specialises in batch processing. Batch sizes vary from a few hundred kilograms to tens of tonnes. We also have continuous processing available with extrusion processes.
Do you sell your own products?
No. Exwold specialises in contract manufacture and in order to avoid any conflicts of interest with our clients, we have chosen to specialise only in contract processing and do not offer our own products.
Can you carry out multi-stage processing?
Yes our expertise and flexible plants allow us to combine processing technologies, for example, we regularly combine blending with our granulation capabilities.
What is your minimum order quantity for processing?
Exwold typically works in the 10 to 1000 tonnes range for clients but processes can be evaluated and adapted on a case by case basis depending on process requirements.
Our pilot facility allows us to produce trial quantities and the High Active Herbicide facility is designed to produce in volumes of 100Kgs upwards.
Can we visit Exwold to perform an audit?
We welcome all our clients to our sites so they can perform audits. We have accreditation to ISO 9001/14001/45001 standards and are looking for continuous improvements in our quality systems, so encourage all customer feedback.

We have sophisticated clean-down procedures for every piece of processing plant and all our plants are accredited with ISO 9001/14001 status.
We operate a plant dedicated to high active herbicides and have warehousing and manufacturing separation between herbicides and insecticides.
Products are tested by a 3rd party analytical company to detect residual impurities to low ppm levels.
Is Exwold sustainable?
Our expertise is in the speciality chemical and agrochemical markets and as a consequence. Exwold does not currently offer services to the food or pharmaceutical markets.
What type of packing does Exwold provide?
Exwold offers packing as an added value to bulk manufacture. We often hold the bulk in stock providing the ultimate flexibility to pack off as required.
We can pack small bottles for high active herbicides (100-1000g).
We are used to handling multiple packing SKUs for products and we pack from 1kg to 1000kgs in a variety of packaging types, including jerricans, paper and foil bags, kegs, FIBCs and bottles.
Can you provide supply product with 2D matrix labelling?
Yes. We have been investing in this capability following the regulatory requirement to include this when supplying crop protection products to countries such as France and Turkey.
How much will you charge me?
We look to offer competitive rates and, since every processing job is bespoke, we evaluate every opportunity on a case by case basis.
We are able to provide indicative prices at early stages of discussion to ensure project viability.
I know I want a granule made but not sure of how, can you help me?
Our technical team can help to determine which technology is best using their expert granulation knowledge and by asking a few simple questions such as granule size, specific physical properties required and application. From this they will suggest the best options to fulfil your needs.
The Technical Development centre can be used to assess whether this technology produces your desired granule and can support customer trials.
