About Us | Censil Silica

Company story

Engineers first, traders second

Every Censil Silica project opens the same way: not with a price list, but with a question. What is the line actually struggling with — a liquid that refuses to become a free-flowing powder, a seasoning that bridges in the hopper, a paste that cleans poorly, a granule that disintegrates too slowly, phosphorus that survives refining? Once that question is written down, choosing a silica grade becomes an engineering exercise rather than a guess.

That habit shapes how we serve formulation plants, blenders, licensed importers and technical distributors across our six tracks — feed additives, food powders, oral care, agrochemicals and industrial fluoride removal. A recommendation only counts when a sample has been run on the customer's own material and the numbers hold up.

Mission

Turn silica selection from trial-and-error into a short, evidence-backed validation loop that any mid-size plant can afford to run.

How we work

Define the process problem in measurable terms before naming any grade.
Send a sample matched to that definition, with a suggested test protocol.
Read the validation data together, then adjust grade or dosage.
Scale only what the data supports — light first order, steady repeat.

Milestones

How the practice took shape

Origin

From product list to problem list

Instead of cataloguing grades, we catalogued the recurring process failures our six industries share — and mapped grades against them.

Phase 1

Wrote the validation playbook

Turned ad-hoc sampling into a repeatable protocol: intake questionnaire, matched sample, test method, compliance file — the same sequence every time.

Phase 2

Proved it in the field

Ran the playbook with early adopters in priority markets; validated trials converted into first orders and, more importantly, into repeats.

Now

One engineering front door

censilsilica.com now carries the whole loop online — grade selection, sample requests, documentation and onboarding, all reachable from a single site.

Trade shows & exhibitions

Meeting customers at international shows

From food and feed ingredients to industrial water treatment, our team presents at leading international exhibitions — running live demonstrations, technical sessions and face-to-face meetings with formulators and refiners worldwide.

2025 Fi Asia · Bangkok

Food & feed anti-caking and carrier solutions — sample wall, grade selector and application discussions with Southeast Asian formulators.

2026 IE expo China · Shanghai

Industrial fluoride removal — live adsorption column demo with before/after water samples (CENSIL 320 substrate screening).

Sustainability & responsibility

Sustainability we can actually prove

Synthetic amorphous silica is an inert, well-characterised material with long-standing approvals in food, feed, oral care and cosmetics. Rather than publish slogans, we anchor our environmental effort in three things we can verify: material safety, dosage efficiency and truthful paperwork.

A material with a clean record

Precipitated silica carries no CLP hazard classification. It holds E 551 status in food, is listed as a feed material, and appears in cosmetics as INCI Hydrated Silica. Being amorphous — not crystalline — it presents no silicosis concern under normal handling.

Less material, same result

A correctly matched grade works at a lower dose. In validated feed and coatings projects, customers halved their addition rates after switching — which shrinks freight tonnage, packaging waste and warehouse space along with the invoice.

Waste avoided at the customer's plant

Silica adsorbents let oil refiners run with less bleaching earth and generate less spent-earth waste. On formulation lines, powders that flow and stay stable mean fewer reworked batches and fewer returns — process efficiency and environmental benefit are the same number.

Paperwork that tells the truth

Our SDS, TDS and compliance files distinguish clearly between validated results and typical values, so customers can face REACH, food-contact and local regulatory audits with documents that hold up under questioning.

Order what the trial justified

Because validation comes before volume, and packaging scales from 20/25 kg bags up to FIBC, customers size orders to real consumption instead of guesswork — less dead stock sitting in warehouses on both ends.

Evidence before announcements

Grade-level environmental data and third-party test reports will appear on this page as each certification is completed — in that order, not the reverse. What we cannot yet prove, we do not yet claim.

On sustainability our bias is deliberate: say less than we can back up. Certifications and environmental figures go public only once they are formally issued and independently checkable.

Our team

Who picks up when you write to us

Censil Silica stays deliberately small: scientists, application engineers and commercial staff who each carry customer projects personally, from the first sample shipment through to standing orders.

Mr. Liu

Founder & General Manager

Sets the brand's direction and personally oversees export operations in the seven markets we serve.

Dr. Zhao

Technical & R&D Director

Runs grade development and validation methodology; spoke on silica adsorbents at AOCS 2025.

Dr. Wu

Chief Scientist

Studies how particle morphology and surface chemistry translate into performance on the customer's line.

David

North America Director

First point of contact for US and Canadian accounts, from initial inquiry to contract supply.

Sophie

Marketing Manager

Turns validation results into technical content and plans our presence at international shows.

Ms. Sun

Sales Manager

Coordinates inquiries, sample logistics and first-order onboarding across all six tracks.

Team

Three functions, one loop

Application engineering

Converts your process complaint into measurable test criteria, then matches a grade against them.

Customer development

Keeps our attention on plants whose problems we can genuinely solve, market by market.

Supply & delivery

Handles mixed-grade consolidation and complete document packs, so a modest first order still ships cleanly and repeats reliably.
