Product Description

HONGYE SILICONE lightweight filled silicone is low-density platinum cured mould silicone tailored for oversized portable casting molds. This light-weight addition curing RTV 2 Silicone Rubber adopts hollow filler Silicone raw materials to cut total mold weight greatly. Different from heavy solid Condensation Curing Silicone Mold Rubber, this portable Mold Making Silicone and Rapid prototyping silicone eases transportation, installation and disassembly for outdoor large sculptures and movable decorative molds.

Product Overview

This lightweight Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Light filler formula reduces overall density without sacrificing elasticity and tear resistance, supporting room temperature and heating dual curing modes. Widely used for outdoor landscape sculpture molds, movable cultural stone, large ornament Prototype silicone , portable display craft molds and bulk rapid prototyping, all formulas accept personalized adjustment.

Technical Specifications

Curing Type: Platinum cured Addition Curing Silicone; Mix Ratio: 1:1 by weight; Working Time (25℃): 30-40 minutes; Room Curing: 4-5 hours; Heating Curing: 80-120℃ rapid curing; Temperature Resistance: -60℃~250℃; Shelf Life: 10 months sealed indoor storage; Certification: FDA Food Grade; Core Advantage: Low density, lightweight, easy to carry, deep full curing, balanced mechanical performance.

Product Features & Advantages

Hollow lightweight filler design drastically lowers mold total weight for convenient moving and installation;

Complete deep curing without thickness limit, uniform lightweight structure for extra large thick molds;

FDA certified Food grade mold silicone, non-toxic and odorless for food decoration and art crafts;

Moderate fluid liquid silicone fills complex sculpture textures evenly without filler precipitation;

High tensile and anti-tear performance, no filler shedding during repeated demolding cycles;

Much lighter and handier than ordinary dense industrial Mold Silicone rubber;

Customized density, hardness and curing time for various portable large mould projects.

Step-by-Step Operation Guide

Mix lightweight silicone A and B components evenly at 1:1 weight ratio for 2 to 3 minutes;

Run vacuum defoaming for 2-5 minutes to eliminate bubbles inside the lightweight silicone;

Pour liquid RTV mold silicone steadily into large portable sculpture molds;

Choose proper curing schedule according to on-site production arrangement;

Demold gently after thorough curing to keep integrated lightweight mold structure intact;

Seal residual silicone tightly and store indoors, avoid long-term heavy extrusion.

Application Scenarios & Buyer Value

Applicable to portable large sculpture casting, outdoor landscape ornaments, movable cultural stone molds, rapid prototyping silicone and event decorative crafts. This lightweight silicone cuts logistics and handling labor costs, reduces onsite installation difficulty, shortens project construction period and improves operational efficiency for outdoor engineering manufacturers.

Certifications and Compliance

This low-density silicone gains FDA food safety certification and ISO industrial quality certification, conforms to international RTV 2 silicone rubber manufacturing standards, satisfying cross-border movable large art casting material demands.

Customization Options

We provide full customization on density grade, color and viscosity, offering lightweight exclusive formulas for High transparency mold silicone and outdoor portable molding projects.

Production Process

Lightweight silicone raw material screening → hollow filler blending → constant temperature synthesis → density and toughness balance testing → finished quality inspection → vacuum sealed packaging.
