How Silicone Brushes and Scrubbers Are Made: A Complete Manufacturing Guide

Silicone brushes and scrubbers are widely used in kitchens, bakeries, bathrooms, and personal care applications. Thanks to their heat resistance, flexibility, and hygiene advantages, they have become a popular alternative to traditional bristle brushes.

For brands and buyers looking to develop custom silicone brushes, understanding the materials, molding processes, and production workflow is essential. This guide explains how silicone brushes are made—from raw material selection to final quality inspection.


What Is a Silicone Brush?

A silicone brush is a cleaning or application tool made from food-grade or industrial-grade silicone. Unlike traditional fiber or nylon brushes, silicone brushes are non-porous, flexible, and resistant to heat and chemicals.

Common applications include:

  • Baking and pastry brushing

  • Oil and sauce spreading

  • Grill and BBQ use

  • Kitchen and bathroom cleaning

  • Cosmetic or craft applications

Most silicone brushes are designed to withstand temperatures from -40°C to 230°C, making them suitable for both freezing and high-heat environments.

Key Advantages of Silicone Brushes

Food-Safe and Non-Toxic

High-quality silicone brushes are made from food-grade silicone, free from BPA and harmful substances. When properly cured, they meet standards such as FDA, LFGB, RoHS, and SGS.

Heat Resistance

Silicone does not melt, deform, or release chemicals under normal baking or cooking temperatures, making it ideal for oven and grill use.

Soft, Durable, and Flexible

The elastic structure allows brushes to reach corners and uneven surfaces without scratching cookware or molds.

Easy to Clean

Silicone surfaces resist oil buildup and stains. Brushes can be washed with water, placed in a dishwasher, or sterilized when required.

Materials and Molding Methods for Silicone Brushes

Different silicone brush designs require different molding technologies. In professional manufacturing, the most common processes include:

Compression Molding (HTV Silicone)

  • Uses solid silicone rubber

  • Suitable for thicker or structured designs

  • Cost-effective for medium to large volumes

Liquid Silicone Rubber (LSR) Injection Molding

  • High precision and consistency

  • Ideal for food-grade and medical-grade products

  • Smooth surface finish and low defect rate

Drip or Overmolding Processes

  • Used for multi-material or soft-touch designs

  • Allows creative shapes and ergonomic handles

At Jewelives, silicone brushes and scrubbers are mainly produced using HTV compression molding and LSR injection molding, depending on product requirements.


Customization Options for Silicone Brushes

OEM and ODM customization plays a key role in brand differentiation. Silicone brushes can be customized in multiple ways:

Appearance

  • Shapes: round, flat, square, or custom designs

  • Colors: standard colors or Pantone-matched shades

  • Effects: solid, translucent, marble, or multi-color

Material Properties

  • Hardness range: 5–80 Shore A

  • Material type: HTV silicone or LSR

  • Safety level: food-grade or medical-grade

  • Transparency: translucent to highly transparent

Branding Methods

  • Logo molded directly into tooling

  • Screen printing

  • Laser engraving

  • Heat transfer printing

Packaging and Logistics

  • Individual polybags

  • Back card or PET boxes

  • Custom color boxes

  • Shipping via air, sea, or express courier


Step-by-Step Silicone Brush Manufacturing Process

  1. Product Design
    Create a 3D structure based on function, ergonomics, and branding needs.

  2. Tooling Development
    Molds are produced using steel, aluminum, or copper, depending on durability and precision requirements.

  3. Raw Material Preparation
    High-quality fumed silicone rubber is selected, mixed with color pigments according to Pantone standards, and weighed precisely.

  4. Molding and Curing
    Silicone is injected or compressed into molds under controlled temperature and pressure.

  5. Demolding and Trimming
    Finished parts are removed and excess material is trimmed.

  6. Secondary Vulcanization
    Heat treatment in an oven (typically 2–4 hours) removes residual catalysts and odors to meet FDA or LFGB standards.

  7. Logo Application
    Branding is added through molding, printing, or engraving if required.

  8. Final Quality Inspection
    Products are checked for appearance, dimensions, material integrity, and safety compliance before packing.

FAQ: Silicone Brushes Manufacturing

Are silicone brushes safe for food contact?
Yes, when made from certified food-grade silicone and properly cured.

What is the difference between HTV and LSR silicone brushes?
HTV suits thicker designs and lower tooling cost, while LSR offers higher precision and consistency.

Can I customize color and logo?
Yes. Colors can be Pantone-matched, and logos can be molded, printed, or engraved.

Do silicone brushes need secondary vulcanization?
Most HTV silicone brushes do. LSR products may not require it.
